Only the root "events" directory stores a dentry. There's no reason to
hold a dentry pointer for every eventfs_inode as it is never set except
for the root "events" eventfs_inode.
Create a eventfs_root_inode structure that holds the events_dir dentry.
The "events" eventfs_inode *is* special, let it have its own descriptor.

There's a couple of if statements in eventfs_root_lookup() that should
never be true. Instead of removing them, add WARN_ON_ONCE() around them.
One is a tracefs_inode not being for eventfs.
The other is a child being freed but still on the parent's children
list. When a child is freed, it is removed from the list under the
same mutex that is held during the iteration.

- Do not update shortest_full in rb_watermark_hit() if the watermark
is hit. The shortest_full field was being updated regardless if
the task was going to wait or not. If the watermark is hit, then
the task is not going to wait, so do not update the shortest_full
field (used by the waker).
- Update shortest_full field before setting the full_waiters_pending flag
In the poll logic, the full_waiters_pending flag was being set
before the shortest_full field was set. If the full_waiters_pending
flag is set, writers will check the shortest_full field which has
the least percentage of data that the ring buffer needs to be
filled before waking up. The writer will check shortest_full if
full_waiters_pending is set, and if the ring buffer percentage filled
is greater than shortest full, then it will call the irq_work to
wake up the waiters.
The problem was that the poll logic set the full_waiters_pending flag
before updating shortest_full, which when zero will always trigger
the writer to call the irq_work to wake up the waiters. The irq_work
will reset the shortest_full field back to zero as the woken waiters
is suppose to reset it.
- There's some optimized logic in the rb_watermark_hit() that is used
in ring_buffer_wait(). Use that helper function in the poll logic
as well.
- Restructure ring_buffer_wait() to use wait_event_interruptible()
The logic to wake up pending readers when the file descriptor is
closed is racy. Restructure ring_buffer_wait() to allow callers
to pass in conditions besides the ring buffer having enough data
in it by using wait_event_interruptible().
- Update the tracing_wait_on_pipe() to call ring_buffer_wait() with
its own conditions to exit the wait loop.

Pull lsm fixes from Paul Moore:
"Two fixes to address issues with the LSM syscalls that we shipped in
Linux v6.8. The first patch might be a bit controversial, but the
second is a rather straightforward fix; more on both below.
The first fix from Casey addresses a problem that should have been
caught during the ~16 month (?) review cycle, but sadly was not. The
good news is that Dmitry caught it very quickly once Linux v6.8 was
released. The core issue is the use of size_t parameters to pass
buffer sizes back and forth in the syscall; while we could have solved
this with a compat syscall definition, given the newness of the
syscalls I wanted to attempt to just redefine the size_t parameters as
u32 types and avoid the work associated with a set of compat syscalls.
However, this is technically a change in the syscall's signature/API
so I can understand if you're opposed to this, even if the syscalls
are less than a week old.
[ Fingers crossed nobody even notices - Linus ]
The second fix is a rather trivial fix to allow userspace to call into
the lsm_get_self_attr() syscall with a NULL buffer to quickly
determine a minimum required size for the buffer. We do have
kselftests for this very case, I'm not sure why I didn't notice the
failure; I'm going to guess stupidity, tired eyes, I dunno. My
apologies we didn't catch this earlier"

Merge tag 'pci-v6.9-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Consolidate interrupt related code in irq.c (Ilpo Järvinen)
- Reduce kernel size by replacing sysfs resource macros with
functions (Ilpo Järvinen)
- Reduce kernel size by compiling sysfs support only when
CONFIG_SYSFS=y (Lukas Wunner)
- Avoid using Extended Tags on 3ware-9650SE Root Port to work around
an apparent hardware defect (Jörg Wedekind)
Resource management:
- Fix an MMIO mapping leak in pci_iounmap() (Philipp Stanner)
- Move pci_iomap.c and other PCI-specific devres code to drivers/pci
(Philipp Stanner)
- Consolidate PCI devres code in devres.c (Philipp Stanner)
Power management:
- Avoid D3cold on Asus B1400 PCI-NVMe bridge, where firmware doesn't
know how to return correctly to D0, and remove previous quirk that
wasn't as specific (Daniel Drake)
- Allow runtime PM when the driver enables it but doesn't need any
runtime PM callbacks (Raag Jadav)
- Drain runtime-idle callbacks before driver removal to avoid races
between .remove() and .runtime_idle(), which caused intermittent
page faults when the rtsx .runtime_idle() accessed registers that
its .remove() had already unmapped (Rafael J. Wysocki)
Virtualization:
- Avoid Secondary Bus Reset on LSI FW643 so it can be assigned to VMs
with VFIO, e.g., for professional audio software on many Apple
machines, at the cost of leaking state between VMs (Edmund Raile)
Error handling:
- Print all logged TLP Prefixes, not just the first, after AER or DPC
errors (Ilpo Järvinen)
- Quirk the DPC PIO log size for Intel Raptor Lake Root Ports, which
still don't advertise a legal size (Paul Menzel)
- Ignore expected DPC Surprise Down errors on hot removal (Smita
Koralahalli)
- Block runtime suspend while handling AER errors to avoid races that
prevent the device form being resumed from D3hot (Stanislaw
Gruszka)
Peer-to-peer DMA:
- Use atomic XA allocation in RCU read section (Christophe JAILLET)
ASPM:
- Collect bits of ASPM-related code that we need even without
CONFIG_PCIEASPM into aspm.c (David E. Box)
- Save/restore L1 PM Substates config for suspend/resume (David E.
Box)
- Update save_save when ASPM config is changed, so a .slot_reset()
during error recovery restores the changed config, not the
.probe()-time config (Vidya Sagar)
Endpoint framework:
- Refactor and improve pci_epf_alloc_space() API (Niklas Cassel)
- Clean up endpoint BAR descriptions (Niklas Cassel)
- Fix ntb_register_device() name leak in error path (Yang Yingliang)
- Return actual error code for pci_vntb_probe() failure (Yang
Yingliang)
Broadcom STB PCIe controller driver:
- Fix MDIO write polling, which previously never waited for
completion (Jonathan Bell)
Cadence PCIe endpoint driver:
- Clear the ARI "Next Function Number" of last function (Jasko-EXT
Wojciech)
Freescale i.MX6 PCIe controller driver:
- Simplify by replacing switch statements with function pointers for
different hardware variants (Frank Li)
- Simplify by using clk_bulk*() API (Frank Li)
- Remove redundant DT clock and reg/reg-name details (Frank Li)
- Add i.MX95 DT and driver support for both Root Complex and Endpoint
mode (Frank Li)
Microsoft Hyper-V host bridge driver:
- Reduce memory usage by limiting ring buffer size to 16KB instead of
4 pages (Michael Kelley)
Qualcomm PCIe controller driver:
- Add X1E80100 DT and driver support (Abel Vesa)
- Add DT 'required-opps' for SoCs that require a minimum performance
level (Johan Hovold)
- Make DT 'msi-map-mask' optional, depending on how MSI interrupts
are mapped (Johan Hovold)
- Disable ASPM L0s for sc8280xp, sa8540p and sa8295p because the PHY
configuration isn't tuned correctly for L0s (Johan Hovold)
- Split dt-binding qcom,pcie.yaml into qcom,pcie-common.yaml and
separate files for SA8775p, SC7280, SC8180X, SC8280XP, SM8150,
SM8250, SM8350, SM8450, SM8550 for easier reviewing (Krzysztof
Kozlowski)
- Enable BDF to SID translation by disabling bypass mode (Manivannan
Sadhasivam)
- Add endpoint MHI support for Snapdragon SA8775P SoC (Mrinmay
Sarkar)
Synopsys DesignWare PCIe controller driver:
- Allocate 64-bit MSI address if no 32-bit address is available (Ajay
Agarwal)
- Fix endpoint Resizable BAR to actually advertise the required 1MB
size (Niklas Cassel)
MicroSemi Switchtec management driver:
- Release resources if the .probe() fails (Christophe JAILLET)
Miscellaneous:
- Make pcie_port_bus_type const (Ricardo B. Marliere)"

No core changes this time around.
New drivers:
- New driver for Renesas R8A779H0 also known as R-Car V4M.
- New driver for the Awinic AW9523/B I2C GPIO expander.
I found this living out-of-tree in OpenWrt as an upstream
attempt had stalled on the finishing line, so I picked it
up and finished the job.
Improvements:
- The Nomadik pin control driver was for years re-used out of
tree for the ST STA chips, and now the IP was re-used in a
MIPS automotive SoC called MobilEyeq5, so it has been split
in pin control and GPIO drivers so the latter can be reused
by MobilEyeq5. (Along with a long list of cleanups.)
- A lot of overall cleanup and tidying up.

Passing a NULL buffer into the lsm_get_self_attr() syscall is a valid
way to quickly determine the minimum size of the buffer needed to for
the syscall to return all of the LSM attributes to the caller.
Unfortunately we/I broke that behavior in commit d7cf3412a9
("lsm: consolidate buffer size handling into lsm_fill_user_ctx()")
such that it returned an error to the caller; this patch restores the
original desired behavior of using the NULL buffer as a quick way to
correctly size the attribute buffer.

Signed-off-by: Paul Moore <paul@paul-moore.com>
Change the size parameters in lsm_list_modules(), lsm_set_self_attr()
and lsm_get_self_attr() from size_t to u32. This avoids the need to
have different interfaces for 32 and 64 bit systems.

As Linus suggested this enables pidfs unconditionally. A key property to
retain is the ability to compare pidfds by inode number (cf. [1]).
That's extremely helpful just as comparing namespace file descriptors by
inode number is. They are used in a variety of scenarios where they need
to be compared, e.g., when receiving a pidfd via SO_PEERPIDFD from a
socket to trivially authenticate a the sender and various other
use-cases.
For 64bit systems this is pretty trivial to do. For 32bit it's slightly
more annoying as we discussed but we simply add a dumb ida based
allocator that gets used on 32bit. This gives the same guarantees about
inode numbers on 64bit without any overflow risk. Practically, we'll
never run into overflow issues because we're constrained by the number
of processes that can exist on 32bit and by the number of open files
that can exist on a 32bit system. On 64bit none of this matters and
things are very simple.
If 32bit also needs the uniqueness guarantee they can simply parse the
contents of /proc/<pid>/fd/<nr>. The uniqueness guarantees have a
variety of use-cases. One of the most obvious ones is that they will
make pidfiles (or "pidfdfiles", I guess) reliable as the unique
identifier can be placed into there that won't be reycled. Also a
frequent request.
Note, I took the chance and simplified path_from_stashed() even further.
Instead of passing the inode number explicitly to path_from_stashed() we
let the filesystem handle that internally. So path_from_stashed() ends
up even simpler than it is now. This is also a good solution allowing
the cleanup code to be clean and consistent between 32bit and 64bit. The
cleanup path in prepare_anon_dentry() is also switched around so we put
the inode before the dentry allocation. This means we only have to call
the cleanup handler for the filesystem's inode data once and can rely
->evict_inode() otherwise.
Aside from having to have a bit of extra code for 32bit it actually ends
up a nice cleanup for path_from_stashed() imho.
Tested on both 32 and 64bit including error injection.

Christophe Leroy did most of the work on this release, first with a few
cleanups on CONFIG_STRICT_KERNEL_RWX and ending with error handling for
when set_memory_XX() can fail. This is part of a larger effort to clean
up all these callers which can fail, modules is just part of it.
This has been sitting on linux-next for about a month without issues.

Pull power management updates from Rafael Wysocki:
"From the functional perspective, the most significant change here is
the addition of support for Energy Models that can be updated
dynamically at run time.
There is also the addition of LZ4 compression support for hibernation,
the new preferred core support in amd-pstate, new platforms support in
the Intel RAPL driver, new model-specific EPP handling in intel_pstate
and more.
Apart from that, the cpufreq default transition delay is reduced from
10 ms to 2 ms (along with some related adjustments), the system
suspend statistics code undergoes a significant rework and there is a
usual bunch of fixes and code cleanups all over.

Serialization rework:
- use SRCU to serialize access to the global GPIO device list, to GPIO device
structs themselves and to GPIO descriptors
- make the GPIO subsystem resilient to the GPIO providers being unbound while
the API calls are in progress
- don't dereference the SRCU-protected chip pointer if the information we need
can be obtained from the GPIO device structure
- move some of the information contained in struct gpio_chip to struct
gpio_device to further reduce the need to dereference the former
- pass the GPIO device struct instead of the GPIO chip to sysfs callback to,
again, reduce the need for accessing the latter
- get GPIO descriptors from the GPIO device, not from the chip for the same
reason
- allow for mostly lockless operation of the GPIO driver API: assure
consistency with SRCU and atomic operations
- remove the global GPIO spinlock
- remove the character device RW semaphore
Core GPIOLIB:
- constify pointers in GPIO API where applicable
- unify the GPIO counting APIs for ACPI and OF
- provide a macro for iterating over all GPIOs, not only the ones that are
requested
- remove leftover typedefs
- pass the consumer device to GPIO core in devm_fwnode_gpiod_get_index() for
improved logging
- constify the GPIO bus type
- don't warn about removing GPIO chips with descriptors still held by users as
we can now handle this situation gracefully
- remove unused logging helpers
- unexport functions that are only used internally in the GPIO subsystem
- set the device type (assign the relevant struct device_type) for GPIO devices
New drivers:
- add the ChromeOS EC GPIO driver
Driver improvements:
- allow building gpio-vf610 with COMPILE_TEST as well as disabling it in
menuconfig (before it was always built for i.MX cofigs)
- count the number of EICs using the device properties instead of hard-coding
it in gpio-eic-sprd
- improve the device naming, extend the debugfs output and add lockdep asserts
to gpio-sim
DT bindings:
- document the 'label' property for gpio-pca9570
- convert aspeed,ast2400-gpio bindings to DT schema
- disallow unevaluated properties for gpio-mvebu
- document a new model in renesas,rcar-gpio
Documentation:
- improve the character device kerneldocs in user-space headers
- add proper documentation for the character device uAPI (both v1 and v2)
- move the sysfs and gpio-mockup docs into the "obsolete" section
- improve naming consistency for GPIO terms
- clarify the line values description for sysfs
- minor docs improvements
- improve the driver API contract for setting GPIO direction
- mark unsafe APIs as deprecated in kerneldocs and suggest replacements
Other:
- remove an obsolete test from selftests

Pull gpio updates from Bartosz Golaszewski:
"The biggest feature is the locking overhaul. Up until now the
synchronization in the GPIO subsystem was broken. There was a single
spinlock "protecting" multiple data structures but doing it wrong (as
evidenced by several places where it would be released when a sleeping
function was called and then reacquired without checking the protected
state).
We tried to use an RW semaphore before but the main issue with GPIO is
that we have drivers implementing the interfaces in both sleeping and
non-sleeping ways as well as user-facing interfaces that can be called
both from process as well as atomic contexts. Both ends converge in
the same code paths that can use neither spinlocks nor mutexes. The
only reasonable way out is to use SRCU and go mostly lockless. To that
end: we add several SRCU structs in relevant places and use them to
assure consistency between API calls together with atomic reads and
writes of GPIO descriptor flags where it makes sense.
This code has spent several weeks in next and has received several
fixes in the first week or two after which it stabilized nicely. The
GPIO subsystem is now resilient to providers being suddenly unbound.
We managed to also remove the existing character device RW semaphore
and the obsolete global spinlock.
Other than the locking rework we have one new driver (for Chromebook
EC), much appreciated documentation improvements from Kent and the
regular driver improvements, DT-bindings updates and GPIOLIB core
tweaks.
Serialization rework:
- use SRCU to serialize access to the global GPIO device list, to
GPIO device structs themselves and to GPIO descriptors
- make the GPIO subsystem resilient to the GPIO providers being
unbound while the API calls are in progress
- don't dereference the SRCU-protected chip pointer if the
information we need can be obtained from the GPIO device structure
- move some of the information contained in struct gpio_chip to
struct gpio_device to further reduce the need to dereference the
former
- pass the GPIO device struct instead of the GPIO chip to sysfs
callback to, again, reduce the need for accessing the latter
- get GPIO descriptors from the GPIO device, not from the chip for
the same reason
- allow for mostly lockless operation of the GPIO driver API: assure
consistency with SRCU and atomic operations
- remove the global GPIO spinlock
- remove the character device RW semaphore
Core GPIOLIB:
- constify pointers in GPIO API where applicable
- unify the GPIO counting APIs for ACPI and OF
- provide a macro for iterating over all GPIOs, not only the ones
that are requested
- remove leftover typedefs
- pass the consumer device to GPIO core in
devm_fwnode_gpiod_get_index() for improved logging
- constify the GPIO bus type
- don't warn about removing GPIO chips with descriptors still held by
users as we can now handle this situation gracefully
- remove unused logging helpers
- unexport functions that are only used internally in the GPIO
subsystem
- set the device type (assign the relevant struct device_type) for
GPIO devices
New drivers:
- add the ChromeOS EC GPIO driver
Driver improvements:
- allow building gpio-vf610 with COMPILE_TEST as well as disabling it
in menuconfig (before it was always built for i.MX cofigs)
- count the number of EICs using the device properties instead of
hard-coding it in gpio-eic-sprd
- improve the device naming, extend the debugfs output and add
lockdep asserts to gpio-sim
DT bindings:
- document the 'label' property for gpio-pca9570
- convert aspeed,ast2400-gpio bindings to DT schema
- disallow unevaluated properties for gpio-mvebu
- document a new model in renesas,rcar-gpio
Documentation:
- improve the character device kerneldocs in user-space headers
- add proper documentation for the character device uAPI (both v1 and v2)
- move the sysfs and gpio-mockup docs into the "obsolete" section
- improve naming consistency for GPIO terms
- clarify the line values description for sysfs
- minor docs improvements
- improve the driver API contract for setting GPIO direction
- mark unsafe APIs as deprecated in kerneldocs and suggest
replacements
Other:
- remove an obsolete test from selftests"

This release sees some exciting changes from David Lechner which
implements some optimisations that have been talked about for a long
time which allows client drivers to pre-prepare SPI messages for
repeated or low latency use. This lets us move work out of latency
sensitive paths and avoid repeating work for frequently performed
operations. As well as being useful in itself this will also be used in
future to allow controllers to directly trigger SPI operations (eg, from
interrupts).
Otherwise this release has mostly been focused on cleanups, plus a
couple of new devices:
- Support for pre-optimising messages.
- A big set of updates from Uwe Kleine-König moving drivers to use APIs
with more modern terminology for controllers.
- Major overhaul of the s3c64xx driver.
- Support for Google GS101 and Samsung Exynos850.
