ALSA: pcm: Fix missing fixup call in compat hw_refine ioctl
The update of rate_num/den and msbits were factored out to
fixup_unreferenced_params() function to be called explicitly after the
hw_refine or hw_params procedure. It's called from
snd_pcm_hw_refine_user(), but it's forgotten in the PCM compat ioctl.
This ended up with the incomplete rate_num/den and msbits parameters
when 32bit compat ioctl is used.
This patch adds the missing call in snd_pcm_ioctl_hw_params_compat().
Reported-by: Meng_Cai@novatek.com.cn

Merge branch 'slab/for-6.6/random_kmalloc' into slab/for-next
Merge the new hardening feature to make heap spraying harder, by GONG, Ruiqi. It creates multiple (16) copies of kmalloc caches, reducing the chance of an attacker-controllable allocation site to land in the same slab as e.g. an allocation site with use-after-free vulnerability. The selection of the copy is derived from the allocation site address, including a per-boot random seed. In line with SLAB deprecation, this is a SLUB only feature, incompatible with SLUB_TINY due to the memory overhead of the extra cache copies. |

super: ensure valid info
For keyed filesystems that recycle superblocks based on s_fs_info or
information contained therein s_fs_info must be kept as long as the
superblock is on the filesystem type super list. This isn't guaranteed
as s_fs_info will be freed latest in sb->kill_sb().
The fix is simply to perform notification and list removal in
kill_anon_super(). Any filesystem needs to free s_fs_info after they
call the kill_*() helpers. If they don't they risk use-after-free right
now so fixing it here is guaranteed that s_fs_info remain valid.
For block backed filesystems notifying in pass sb->kill_sb() in
deactivate_locked_super() remains unproblematic and is required because
multiple other block devices can be shut down after kill_block_super()
has been called from a filesystem's sb->kill_sb() handler. For example,
ext4 and xfs close additional devices. Block based filesystems don't
depend on s_fs_info (btrfs does use s_fs_info but also uses
kill_anon_super() and not kill_block_super().).
Sorry for that braino. Goal should be to unify this behavior during this
cycle obviously. But let's please do a simple bugfix now.

Scheduler changes for v6.6:
- The biggest change is introduction of a new iteration of the
SCHED_FAIR interactivity code: the EEVDF ("Earliest Eligible Virtual
Deadline First") scheduler.
EEVDF too is a virtual-time scheduler, with two parameters (weight
and relative deadline), compared to CFS that had weight only.
It completely reworks the base scheduler: placement, preemption,
picking -- everything.
LWN.net, as usual, has a terrific writeup about EEVDF:
https://lwn.net/Articles/925371/
Preemption (both tick and wakeup) is driven by testing against
a fresh pick. Because the tree is now effectively an interval
tree, and the selection is no longer the 'leftmost' task,
over-scheduling is less of a problem. A lot of the CFS
heuristics are removed or replaced by more natural latency-space
parameters & constructs.
In terms of expected performance regressions: we'll and can fix
everything where a 'good' workload misbehaves with the new scheduler,
but EEVDF inevitably changes workload scheduling in a binary fashion,
hopefully for the better in the overwhelming majority of cases,
but in some cases it won't, especially in adversarial loads that
got lucky with the previous code, such as some variants of hackbench.
We are trying hard to err on the side of fixing all performance
regressions, but we expect some inevitable post-release iterations
of that process.
- Improve load-balancing on hybrid x86 systems: enable cluster
scheduling (again).
- Improve & fix bandwidth-scheduling on nohz systems.
- Improve bandwidth-throttling.
- Use lock guards to simplify and de-goto-ify control flow.
- Misc improvements, cleanups and fixes.

- Avoid the baremetal decompressor code when booting on an EFI machine.
This is mandated by the current tightening of EFI executables requirements when used in a secure boot scenario. More specifically, an EFI executable cannot have a single section with RWX permissions, which conflicts with the in-place kernel decompression that is done today. Instead, the things required by the booting kernel image are done in the EFI stub now.

Updates for the CPU hotplug core:
- Support partial SMT enablement.
So far the sysfs SMT control only allows to toggle between SMT on and
off. That's sufficient for x86 which usually has at max two threads
except for the Xeon PHI platform which has four threads per core.
Though PowerPC has up to 16 threads per core and so far it's only
possible to control the number of enabled threads per core via a
command line option. There is some way to control this at runtime, but
that lacks enforcement and the usability is awkward.
This update expands the sysfs interface and the core infrastructure to
accept numerical values so PowerPC can build SMT runtime control for
partial SMT enablement on top.
The core support has also been provided to the PowerPC maintainers who
added the PowerPC related changes on top.
- Minor cleanups and documentation updates.

Pull btrfs updates from David Sterba:
"No new features, the bulk of the changes are fixes, refactoring and
cleanups. The notable fix is the scrub performance restoration after
rewrite in 6.4, though still only partial.
Fixes:
- scrub performance drop due to rewrite in 6.4 partially restored:
- do IO grouping by blg_plug/blk_unplug again
- avoid unnecessary tree searches when processing stripes, in
extent and checksum trees
- the drop is noticeable on fast PCIe devices, -66% and restored
to -33% of the original
- backports to 6.4 planned
- handle more corner cases of transaction commit during orphan
cleanup or delayed ref processing
- use correct fsid/metadata_uuid when validating super block
- copy directory permissions and time when creating a stub subvolume
Core:
- debugging feature integrity checker deprecated, to be removed in
6.7
- in zoned mode, zones are activated just before the write, making
error handling easier, now the overcommit mechanism can be enabled
again which improves performance by avoiding more frequent flushing
- v0 extent handling completely removed, deprecated long time ago
- error handling improvements
- tests:
- extent buffer bitmap tests
- pinned extent splitting tests
- cleanups and refactoring:
- compression writeback
- extent buffer bitmap
- space flushing, ENOSPC handling"

New code for 6.6:
* Make large writes to the page cache fill sparse parts of the cache
with large folios, then use large memcpy calls for the large folio.
* Track the per-block dirty state of each large folio so that a
buffered write to a single byte on a large folio does not result in a
(potentially) multi-megabyte writeback IO.
* Allow some directio completions to be performed in the initiating
task's context instead of punting through a workqueue. This will
reduce latency for some io_uring requests.

Merge tag 'iomap-6.6-merge-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull iomap updates from Darrick Wong:
"We've got some big changes for this release -- I'm very happy to be
landing willy's work to enable large folios for the page cache for
general read and write IOs when the fs can make contiguous space
allocations, and Ritesh's work to track sub-folio dirty state to
eliminate the write amplification problems inherent in using large
folios.
As a bonus, io_uring can now process write completions in the caller's
context instead of bouncing through a workqueue, which should reduce
io latency dramatically. IOWs, XFS should see a nice performance bump
for both IO paths.
Summary:
- Make large writes to the page cache fill sparse parts of the cache
with large folios, then use large memcpy calls for the large folio.
- Track the per-block dirty state of each large folio so that a
buffered write to a single byte on a large folio does not result in
a (potentially) multi-megabyte writeback IO.
- Allow some directio completions to be performed in the initiating
task's context instead of punting through a workqueue. This will
reduce latency for some io_uring requests"

Pull erofs updates from Gao Xiang:
"In this cycle, a xattr bloom filter feature is introduced to speed up
negative xattr lookups, which was originally suggested by Alexander
for Composefs use cases.
Additionally, the DEFLATE algorithm is now supported, which can be
used together with hardware accelerators for our cloud workloads. Each
supported compression algorithm can be selected on a per-file basis
for specific access patterns too.
There are also some random fixes and cleanups as usual:
- Support xattr bloom filter to optimize negative xattr lookups
- Support DEFLATE compression algorithm as an alternative
- Fix a regression that ztailpacking pclusters don't release properly
- Avoid warning dedupe and fragments features anymore
- Some folio conversions and cleanups"
