3fa5975b07 scsi: initio: Remove redundant assignment to pointer scb
The variable scb is assigned a value but it is never read. The assignment
is redundant and can be removed. Also replace the != NULL check with the
more usual non-null check idiom.

Cleans up clang scan build warning:

drivers/scsi/initio.c:1169:9: warning: Although the value stored to 'scb'
is used in the enclosing expression, the value is never actually read
from 'scb' [deadcode.DeadStores]

2745ce0e6d scsi: mpi3mr: Refresh SAS ports during soft reset
Update the host's SAS ports if there is change in port id or phys. If the
port id is changed, then the driver updates it. If some phys are
enabled/disabled during reset, then driver updates them in STL.

Check for the responding expander devices and update the device handle if
it got changed. Register the expander with STL if it got added during reset
and unregister the expander device if it got removed during reset.

[mkp: include fix for zeroday warning]

6c4148ce7c scsi: ufs: wb: Add explicit flush sysfs attribute
There is the following quirk to bypass "WB Flush" in Write Booster.

	- UFSHCI_QUIRK_SKIP_MANUAL_WB_FLUSH_CTRL

If this quirk is not set, there is no knob that can control "WB Flush".

There are three flags that control Write Booster Feature:

	1. WB ON/OFF
	2. WB Hibern Flush ON/OFF (implicitly)
	3. WB Flush ON/OFF (explicit)

The sysfs attribute that controls the WB was implemented. (1)

In the case of "Hibern Flush", it is always good to turn on.  Control may
not be required. (2)

Finally, "Flush" may be necessary because the Auto-Hibern8 is not supported
in a specific environment.  So the sysfs attribute that controls this is
necessary. (3)

0f85e74756 scsi: ufs: core: Use local_clock() for debugging timestamps
CLOCK_MONOTONIC is not advanced when the system is in suspend. This becomes
problematic when debugging issues related to suspend-resume: the timestamps
printed by ufshcd_print_trs can not be correlated with dmesg entries, which
are timestamped with local_clock().

Change the used clock to local_clock() for the informational timestamp
variables and adds mirroring *_local_clock instances for variables used in
subsequent derevations (to not change the semantics of those derevations).

b7dbc686f6 scsi: ufs: ufs-mediatek: Support clk-scaling to optimize power consumption
Provide clk-scaling feature in MediaTek UFS platforms.

MediaTek platform supports clk-scaling by switching parent clock mux of
UFSHCI main clocks: ufs_sel.

The driver needs to prevent changing the rate of ufs_sel because its parent
PLL clock may be shared between multiple IPs. In order to achieve this
goal, the maximum and minimum clock rates of ufs_sel defined in dts should
match the rate of "ufs_sel_max_src" and "ufs_sel_min_src" respectively.

96f86ff083 perf tools changes for v6.0: 2nd batch
- 'perf c2c' now supports ARM64, adjust its output to cope with differences with
   what is in x86_64. Now go find false sharing on ARM64 (at least Neoverse) as well!
 
 - Refactor the JSON processing, making the output more compact and thus reducing the
   size of the resulting perf binary.
 
 - Improvements for 'perf offcpu' profiling, including tracking child processes.
 
 - Update Intel JSON metrics and events files for broadwellde, broadwellx,
   cascadelakex, haswellx, icelakex, ivytown, jaketown, knightslanding,
   sapphirerapids, skylakex and snowridgex.
 
 - Add 'perf stat' JSON output and a 'perf test' entry for it.
 
 - Ignore memfd and anonymous mmap events if jitdump present.
 
 - Refactor 'perf test' shell tests allowing subdirs.
 
 - Fix an error handling path in 'parse_perf_probe_command()'
 
 - Fixes for the guest Intel PT tracing patchkit in the 1st batch of this merge window.
 
 - Print debuginfod queries if -v option is used, to explain delays in processing when
   debuginfo servers are enabled to fetch DSOs with richer symbol tables.
 
 - Improve error message for 'perf record -p not_existing_pid'
 
 - Fix openssl and libbpf feature detection.
 
 - Add PMU pai_crypto event description for IBM z16 on 'perf list'.
 
 - Fix typos and duplicated words on comments in various places.

8549a26308 afs: Enable multipage folio support
Enable multipage folio support for the afs filesystem.

Support has already been implemented in netfslib, fscache and cachefiles
and in most of afs, but I've waited for Matthew Wilcox's latest folio
changes.

Note that it does require a change to afs_write_begin() to return the
correct subpage.  This is a "temporary" change as we're working on
getting rid of the need for ->write_begin() and ->write_end()
completely, at least as far as network filesystems are concerned - but
it doesn't prevent afs from making use of the capability.

7391db6459 perf test: Refactor shell tests allowing subdirs
This is a prelude to adding more tests to shell tests and in order to
support putting those tests into subdirectories, I need to change the
test code that scans/finds and runs them.

To support subdirs I have to recurse so it's time to refactor the code
to allow this and centralize the shell script finding into one location
and only one single scan that builds a list of all the found tests in
memory instead of it being duplicated in 3 places.

This code also optimizes things like knowing the max width of desciption
strings (as we can do that while we scan instead of a whole new pass of
opening files).

It also more cleanly filters scripts to see only *.sh files thus
skipping random other files in directories like *~ backup files, other
random junk/data files that may appear and the scripts must be
executable to make the cut (this ensures the script lib dir is not seen
as scripts to run).

This avoids perf test running previous older versions of test scripts
that are editor backup files as well as skipping perf.data files that
may appear and so on.
