In shrink_folio_list(), demote_folio_list() can be called 2 times.
Currently stat->nr_demoted will only store the last nr_demoted( the later
nr_demoted is always zero, the former nr_demoted will get lost), as a
result number of demoted pages is not accurate.
Accumulate the nr_demoted count across multiple calls to
demote_folio_list(), ensuring accurate reporting of demotion statistics.

Commit c1b3bb73d5 ("mm/zsmalloc: use zpdesc in

However, the function is only used when CONFIG_DEBUG_VM=y.
When building with LLVM=1 and W=1 option, the following warning is
generated:
$ make -j12 W=1 LLVM=1 mm/zsmalloc.o
mm/zsmalloc.c:455:20: error: function 'is_first_zpdesc' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration]

1 error generated.
Fix the warning by adding __maybe_unused attribute to the function.
No functional change intended.

Scenario:
User processe are requesting a large amount of memory and keep page active.
Then a module continuously requests memory from ZONE_DMA32 area.
Memory reclaim will be triggered due to ZONE_DMA32 watermark alarm reached.
However pages in the LRU(active_anon) list are mostly from
the ZONE_NORMAL area.
Reproduce:
Terminal 1: Construct to continuously increase pages active(anon).
mkdir /tmp/memory
mount -t tmpfs -o size=1024000M tmpfs /tmp/memory
dd if=/dev/zero of=/tmp/memory/block bs=4M
tail /tmp/memory/block
Terminal 2:
vmstat -a 1
active will increase.

About the Fixes:
Why did it take eight years to be discovered?
The problem requires the following conditions to occur:
1. The device memory should be large enough.
2. Pages in the LRU(active_anon) list are mostly from the ZONE_NORMAL area.
3. The memory in ZONE_DMA32 needs to reach the watermark.
If the memory is not large enough, or if the usage design of ZONE_DMA32
area memory is reasonable, this problem is difficult to detect.
notes:
The problem is most likely to occur in ZONE_DMA32 and ZONE_NORMAL,
but other suitable scenarios may also trigger the problem.

Tomasz has reported that his device, Generalplus Technology Inc. 808 Camera,

$ ls -l /dev/video*
zsh: no matches found: /dev/video*
[ 7.230599] usb 3-2: Found multiple Units with ID 5
This particular device is non-compliant, having both the Output Terminal
and Processing Unit with ID 5. uvc_scan_fallback, though, is able to build
a chain. However, when media elements are added and uvc_mc_create_links
call uvc_entity_by_id, it will get the incorrect entity,
media_create_pad_link will WARN, and it will fail to register the entities.
In order to reinstate support for such devices in a timely fashion,
reverting the fix for these warnings is appropriate. A proper fix that
considers the existence of such non-compliant devices will be submitted in
a later development cycle.

Since commit bede169618 ("kbuild: enable objtool for *.mod.o and
additional kernel objects"), Clang LTO builds do not perform any
optimizations when CONFIG_OBJTOOL is disabled (e.g., for ARCH=arm64).
This is because every LLVM bitcode file is immediately converted to
ELF format before the object files are linked together.
This commit fixes the breakage.

Due to the fact that runtime const ELF sections are named without a
leading period or double underscore, the RSTRIP logic that removes the
static RELA sections from vmlinux fails to identify them. This results
in a situation like below, where some sections that were supposed to get
removed are left behind.
[Nr] Name Type Address Off Size ES Flg Lk Inf Al
[58] runtime_shift_d_hash_shift PROGBITS ffffffff83500f50 2900f50 000014 00 A 0 0 1

[63] .relaruntime_ptr_USER_PTR_MAX RELA 0000000000000000 55b6ff0 000d50 18 I 70 62 8
So tweak the match expression to strip all sections starting with .rel.
While at it, consolidate the logic used by RISC-V, s390 and x86 into a
single shared Makefile library command.

As SMB protocol distinguish between symlink to directory and symlink to
file, add some mechanism to disallow resolving incompatible types.
When SMB symlink is of the directory type, ensure that its target path ends
with slash. This forces Linux to not allow resolving such symlink to file.
And when SMB symlink is of the file type and its target path ends with
slash then returns an error as such symlink is unresolvable. Such symlink
always points to invalid location as file cannot end with slash.
As POSIX server does not distinguish between symlinks to file and symlink
directory, do not apply this change for symlinks from POSIX SMB server. For
POSIX SMB servers, this change does nothing.
This mimics Windows behavior of native SMB symlinks.

This change implements support for creating new symlink in WSL-style by
Linux cifs client when -o reparse=wsl mount option is specified. WSL-style
symlink uses reparse point with tag IO_REPARSE_TAG_LX_SYMLINK and symlink
target location is stored in reparse buffer in UTF-8 encoding prefixed by
32-bit flags. Flags bits are unknown, but it was observed that WSL always
sets flags to value 0x02000000. Do same in Linux cifs client.
New symlinks would be created in WSL-style only in case the mount option
-o reparse=wsl is specified, which is not by default. So default CIFS
mounts are not affected by this change.

There are now more servers which advertise support for IAKerb (passthrough
Kerberos authentication via proxy). IAKerb is a public extension industry
standard Kerberos protocol that allows a client without line-of-sight
to a Domain Controller to authenticate. There can be cases where we
would fail to mount if the server only advertises the OID for IAKerb
in SPNEGO/GSSAPI. Add code to allow us to still upcall to userspace
in these cases to obtain the Kerberos ticket.

struct FILE_ALL_INFO for level 263 (0x107) used by QPathInfo does not have
any IndexNumber, AccessFlags, IndexNumber1, CurrentByteOffset, Mode or
AlignmentRequirement members. So remove all of them.
Also adjust code in move_cifs_info_to_smb2() function which converts struct
FILE_ALL_INFO to struct smb2_file_all_info.
Fixed content of struct FILE_ALL_INFO was verified that is correct against:
* [MS-CIFS] section 2.2.8.3.10 SMB_QUERY_FILE_ALL_INFO
* Samba server implementation of trans2 query file/path for level 263
* Packet structure tests against Windows SMB servers
This change fixes CIFSSMBQFileInfo() and CIFSSMBQPathInfo() functions which
directly copy received FILE_ALL_INFO network buffers into kernel structures
of FILE_ALL_INFO type.
struct FILE_ALL_INFO is the response structure returned by the SMB server.
So the incorrect definition of this structure can lead to returning bogus
information in stat() call.

CIFS client is currently able to parse NFS-style symlinks, but is not able
to create them. This functionality is useful when the mounted SMB share is
used also by Windows NFS server (on Windows Server 2012 or new). It allows
interop of symlinks between SMB share mounted by Linux CIFS client and same
export from Windows NFS server mounted by some NFS client.
New symlinks would be created in NFS-style only in case the mount option
-o reparse=nfs is specified, which is not by default. So default CIFS
mounts are not affected by this change.

When block drivers or the core block code perform allocations with a
frozen queue, this could try to recurse into the block device to
reclaim memory and deadlock. Thus all allocations done by a process
that froze a queue need to be done without __GFP_IO and __GFP_FS.
Instead of tying to track all of them down, force a noio scope as
part of freezing the queue.
Note that nvme is a bit of a mess here due to the non-owner freezes,
and they will be addressed separately.

die executes holding the spinlock of &die.lock and unlock
it after printing the oops message.
However in the code if the notify_die() returns NOTIFY_STOP
, die() exit with returning 1 but never unlocked the spinlock.
Fix this by adding spin_unlock_irq(&die.lock) before returning.

struct inet_diag_handler *
return !cmpxchg((const struct inet_diag_handler**)&inet_diag_table[type],

While hexagon's cmpxchg assigns an integer value to a variable of this

Update this assignment to cast 0 to the correct type.

Pull ACPI fixes from Rafael Wysocki:
"Add a new ACPI-related quirk for Vexia EDU ATLA 10 tablet 5V (Hans de
Goede) and fix the MADT parsing code so that CPUs with different entry
types (LAPIC and x2APIC) are initialized in the order in which they
appear in the MADT as required by the ACPI specification (Zhang Rui)"
* tag 'acpi-6.14-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
x86/acpi: Fix LAPIC/x2APIC parsing order
ACPI: x86: Add skip i2c clients quirk for Vexia EDU ATLA 10 tablet 5V
- Add missing error handling for syscore_suspend() to the hibernation
core code (Wentao Liang).
- Revert a commit that added unused macros (Andy Shevchenko).
- Synchronize the runtime PM status of devices that were runtime-
suspended before a system-wide suspend and need to be resumed during
the subsequent system-wide resume transition (Rafael Wysocki).
- Clean up the teo cpuidle governor and make the handling of short idle
intervals in it consistent regardless of the properties of idle
states supplied by the cpuidle driver (Rafael Wysocki).
- Fix some boost-related issues in cpufreq (Lifeng Zheng).
- Fix build issues in the s3c64xx and airoha cpufreq drivers (Viresh
Kumar).
- Remove unconditional binding of schedutil governor kthreads to the
affected CPUs if the cpufreq driver indicates that updates can happen
from any CPU (Christian Loehle).
