Turn send_sig_info(SIGSTOP) into send_signal_locked(SIGSTOP) and move it
from ptrace_attach() to ptrace_set_stopped().
This looks more logical and avoids lock(siglock) right after unlock().

Instead of popping only the maximum element from the heap during each
iteration, we now pop the two largest elements at once. Although this
introduces an additional comparison to determine the second largest
element, it enables a reduction in the height of the tree by one during
the heapify operations starting from root's left/right child. This
reduction in tree height by one leads to a decrease of one comparison and
one swap.
This optimization results in saving approximately 0.5 * n swaps without
increasing the number of comparisons. Additionally, the heap size during
heapify is now one less than the original size, offering a chance for
further reduction in comparisons and swaps.
The following experimental data is based on the array generated using
get_random_u32().
| N | swaps (old) | swaps (new) | comparisons (old) | comparisons (new) |
|-------|-------------|-------------|-------------------|-------------------|
| 1000 | 9054 | 8569 | 10328 | 10320 |

Patch series "lib/sort: Optimize the number of swaps and comparisons".
This patch series aims to optimize the heapsort algorithm, specifically
targeting a reduction in the number of swaps and comparisons required.
This patch (of 2):
Currently, when searching for the sift-down path and encountering equal
elements, the algorithm chooses the left child. However, considering that
the height of the right subtree may be one less than that of the left
subtree, selecting the right child in such cases can potentially reduce
the number of comparisons and swaps.
For instance, when sorting an array of 10,000 identical elements, the
current implementation requires 247,209 comparisons. With this patch, the
number of comparisons can be reduced to 227,241.

All parameters of posix messages queues (queues_max/msg_max/msgsize_max)
end up being limited by RLIMIT_MSGQUEUE. The code in mqueue_get_inode is
where that limiting happens.
The RLIMIT_MSGQUEUE is bound to the user namespace and is counted
hierarchically.
We can allow root in the user namespace to modify the posix messages

After 25b21cb2f6 ("[PATCH] IPC namespace core") and 4e9823111b
("[PATCH] IPC namespace - shm") the shared memory page count stopped being
global and started counting per ipc namespace. The documentation and
shmget(2) still says that shmall is a global option.
shmget(2):
SHMALL System-wide limit on the total amount of shared memory, measured in
units of the system page size. On Linux, this limit can be read and
modified via /proc/sys/kernel/shmall.
I think the changes made in 2006 should be documented.

Patch series "Allow to change ipc/mq sysctls inside ipc namespace", v3.
Right now ipc and mq limits count as per ipc namespace, but only real root
can change them. By default, the current values of these limits are such
that it can only be reduced. Since only root can change the values, it is
impossible to reduce these limits in the rootless container.
We can allow limit changes within ipc namespace because mq parameters are
limited by RLIMIT_MSGQUEUE and ipc parameters are not limited to anything
other than cgroups.
This patch (of 3):
Rootless containers are not allowed to modify kernel IPC parameters.
All default limits are set to such high values that in fact there are no
limits at all. All limits are not inherited and are initialized to
default values when a new ipc_namespace is created.
For new ipc_namespace:
size_t ipc_ns.shm_ctlmax = SHMMAX; // (ULONG_MAX - (1UL << 24))
size_t ipc_ns.shm_ctlall = SHMALL; // (ULONG_MAX - (1UL << 24))
int ipc_ns.shm_ctlmni = IPCMNI; // (1 << 15)
int ipc_ns.shm_rmid_forced = 0;
unsigned int ipc_ns.msg_ctlmax = MSGMAX; // 8192
unsigned int ipc_ns.msg_ctlmni = MSGMNI; // 32000
unsigned int ipc_ns.msg_ctlmnb = MSGMNB; // 16384
The shm_tot (total amount of shared pages) has also ceased to be global,
it is located in ipc_namespace and is not inherited from anywhere.
In such conditions, it cannot be said that these limits limit anything.
The real limiter for them is cgroups.
If we allow rootless containers to change these parameters, then it can
only be reduced.

Optimize the min_heapify() function, resulting in a significant reduction
of approximately 50% in the number of comparisons for large random inputs,
while maintaining identical results.
The current implementation performs two comparisons per level to identify
the minimum among three elements. In contrast, the proposed bottom-up
variation uses only one comparison per level to assess two children until
reaching the leaves. Then, it sifts up until the correct position is
determined.
Typically, the process of sifting down proceeds to the leaf level,
resulting in O(1) secondary comparisons instead of log2(n). This
optimization significantly reduces the number of costly indirect function
calls and improves overall performance.

LLVM moved their issue tracker from their own Bugzilla instance to GitHub
issues. While all of the links are still valid, they may not necessarily
show the most up to date information around the issues, as all updates
will occur on GitHub, not Bugzilla.
Another complication is that the Bugzilla issue number is not always the
same as the GitHub issue number. Thankfully, LLVM maintains this mapping
through two shortlinks:
https://llvm.org/bz<num> -> https://bugs.llvm.org/show_bug.cgi?id=<num>
https://llvm.org/pr<num> -> https://github.com/llvm/llvm-project/issues/<mapped_num>
Switch all "https://bugs.llvm.org/show_bug.cgi?id=<num>" links to the
"https://llvm.org/pr<num>" shortlink so that the links show the most up to
date information. Each migrated issue links back to the Bugzilla entry,
so there should be no loss of fidelity of information here.

reviews.llvm.org was LLVM's Phabricator instances for code review. It has
been abandoned in favor of GitHub pull requests. While the majority of
links in the kernel sources still work because of the work Fangrui has
done turning the dynamic Phabricator instance into a static archive, there
are some issues with that work, so preemptively convert all the links in
the kernel sources to point to the commit on GitHub.
Most of the commits have the corresponding differential review link in the
commit message itself so there should not be any loss of fidelity in the

ilog2() rounds down, so for example when PowerPC 85xx sets CONFIG_NR_CPUS
to 24, we will only allocate 4 bits to store the number of CPUs instead of
5. Use bits_per() instead, which rounds up. Found by code inspection.
The effect of this would probably be a misaccounting when doing NUMA
balancing, so to a user, it would only be a performance penalty. The
effects may be more wide-spread; it's hard to tell.

Here are some driver core fixes, a kobject fix, and a documentation
update for 6.8-rc5. In detail these changes are:
- devlink fixes for reported issues with 6.8-rc1
- topology scheduling regression fix that has been reported by many
- kobject loosening of checks change in -rc1 is now reverted as some
codepaths seemed to need the checks
- documentation update for the CVE process. Has been reviewed by
many, the last minute change to the document was to bring the .rst
format back into the the new style rules, the contents did not
change.
All of these, except for the documentation update, have been in
linux-next for over a week. The documentation update has been reviewed
for weeks by a group of developers, and in public for a week and the
wording has stabilized for now. If future changes are needed, we can do
so before 6.8-final is out (or anytime after that.)

Fix to search a field from the structure which has anonymous union
correctly.
Since the reference `type` pointer was updated in the loop, the search
loop suddenly aborted where it hits an anonymous union. Thus it can not
find the field after the anonymous union. This avoids updating the
cursor `type` pointer in the loop.

* Fail instead of skipping tests if open(), e.g. of /dev/kvm, fails with an

* Fix TSC related bugs in several Hyper-V selftests.
* Fix a bug in the dirty ring logging test where a sem_post() could be left

* Relax the dirty log split test's assertions on 4KiB mappings to fix false

- Fix the #ifndef that didn't have CONFIG_ on HAVE_DYNAMIC_FTRACE_WITH_REGS
The fix to have dynamic trampolines work with x86 broke arm64 as
the config used in the #ifdef was HAVE_DYNAMIC_FTRACE_WITH_REGS and not
CONFIG_HAVE_DYNAMIC_FTRACE_WITH_REGS which removed the fix that the
previous fix was to fix.
- Fix tracing_on state
The code to test if "tracing_on" is set used ring_buffer_record_is_on()
which returns false if the ring buffer isn't able to be written to.
But the ring buffer disable has several bits that disable it.
One is internal disabling which is used for resizing and other
modifications of the ring buffer. But the "tracing_on" user space
visible flag should only report if tracing is actually on and not
internally disabled, as this can cause confusion as writing "1"
when it is disabled will not enable it.
Instead use ring_buffer_record_is_set_on() which shows the user space
visible settings.
- Fix a false positive kmemleak on saved cmdlines
Now that the saved_cmdlines structure is allocated via alloc_page()
and not via kmalloc() it has become invisible to kmemleak.
The allocation done to one of its pointers was flagged as a
dangling allocation leak. Make kmemleak aware of this allocation
and free.
- Fix synthetic event dynamic strings.
A update that cleaned up the synthetic event code removed the
return value of trace_string(), and had it return zero instead
of the length, causing dynamic strings in the synthetic event
to always have zero size.
- Clean up documentation and header files for seq_buf
