There is a comment in vfs_prepare_mode() that says:
Note that it's currently valid for @type to be 0 if a directory is
created. Filesystems raise that flag individually and we need to check
whether each filesystem can deal with receiving S_IFDIR from the vfs
before we enforce a non-zero type.
It is safe to do this clean-up except that three filesystems (fuse,
cifs, and coda) forward the mkdir @mode unchanged to something outside
the kernel. Mask S_IFDIR back out in coda_mkdir(), fuse_mkdir() and
cifs_mkdir() so that what is sent outside the kernel is unchanged.
Their maintainers can drop the mask once they have confirmed it is safe.

Commit 292db66afd ("ACPICA: Unbreak tools build after switching over

sort of nasty to the acpi_ut_safe_strncpy() definition to unbreak ACPICA
tools builds broken by commit 97f7d3f9c9 ("ACPICA: Replace strncpy()
with strscpy_pad() in acpi_ut_safe_strncpy()"). However, that #ifdef
effectively produces dead code when tools are built because they don't
call acpi_ut_safe_strncpy().
Accordingly, drop the existing definition of acpi_ut_safe_strncpy() and
define it as a strscpy_pad() alias.

A hotplug or link-loss event can tear down the MST topology
(setting mgr->mst_state = false and mgr->mst_primary = NULL) concurrently
with a caller invoking drm_dp_mst_topology_queue_probe(). Since the check
is already performed under mgr->lock, the condition is not a programming
error but a valid race -- the topology was valid when the caller decided
to call this function, but was torn down before the lock was acquired.
Replace the drm_WARN_ON() with a graceful early return. This eliminates
spurious kernel warnings and the resulting compositor crashes observed
when connecting/disconnecting DP MST monitors, while keeping the correct
behavior of doing nothing when MST is not active. A drm_dbg_mst() trace
is added so the skipped probe remains observable under MST debug logging.
The existing WARN_ON(mgr->mst_primary) in drm_dp_mst_topology_mgr_set_mst()
already catches the case where the topology is initialized twice, so no
diagnostic coverage is lost.

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace
and kernelspace coding, or when dealing with uapi headers that
rather should use __ASSEMBLER__ instead. So let's standardize now
on the __ASSEMBLER__ macro that is provided by the compilers.

Checksum verification is needed
1. for crash kernels. In a crash, we can't be sure the kernel is
intact.
2. if we're worried about relocating the kernel into a region used by
some DMA that wasn't properly cancelled.
If KHO is enabled then relocations will happen to KHO scratch, which
is free from DMA regions.
If we used CMA to allocate segments then relocations are not going to
happen at all.
Therefore, we can safely disable checksum verification in both of those
cases.
Instead of adding a new variable to purgatory, just skip adding regions
and save the default value of SHA256 hash.
Saves ~250ms on my 4.0 GHz CPU. This is an important saving for the

If xfs_metadir_create() fails in xfs_dqinode_metadir_create(), the current
code returns directly, leaking the allocated update and transaction state.
If the subsequent commit fails, the caller-owned inode reference is left
behind.
Fix this memory leak by routing the create failure path through
xfs_metadir_cancel(). For both create and commit failures, finish and
release any inode returned to the caller, mirroring the unwind pattern in
xfs_metadir_mkdir().
The bug was first flagged by an experimental analysis tool we are
developing for kernel memory-management bugs while analyzing
v6.13-rc1. The tool is still under development and is not yet publicly
available. Manual inspection confirms that the bug is still
present in v7.1.1.
An x86_64 allyesconfig build showed no new warnings. Runtime validation
used kprobe fault injection during `mount -o uquota` on a metadir XFS
image. Injecting xfs_metadir_create() reproduced the old active-update path
that left mount stuck later in mount setup; after this change, the same
injection reported cancel_hits=1 and irele_hits=1. Injecting
xfs_metadir_commit() exercised the old inode-reference leak path; after
this change, it reported irele_hits=1.

xfs_qm_dqpurge() gets a locked buffer from xfs_dquot_use_attached_buf().
If xfs_qm_dqflush() fails, the error path skips xfs_buf_relse() and then
calls xfs_dquot_detach_buf(), which tries to lock the same buffer again.
Release the buffer after xfs_qm_dqflush() returns so the error path drops
the caller hold and unlocks the buffer before the dquot is detached,
matching the other dqflush callers.

We do unneeded "double free" (emptying an empty list) in one case.
At the same time we shadow a real error code. Address them by
refactoring the code in question.
Both are not critical issues at all, they just make code robust
against any possible future changes in the flow.

The ELAN1300 touchpad with HID ID 04F3:3104 on the ASUS VivoBook
X513UA_KM513UA exhibits severe pointer jumps and erratic movement when
the I2C bus operates at 400 kHz.
The system DSDT describes the touchpad using an I2cSerialBusV2 resource
with a speed of 0x00061A80, corresponding to 400 kHz, on the
AMDI0010:03 controller.
At this speed, libinput repeatedly reports:
kernel bug: Touch jump detected and discarded
Add ELAN1300 to i2c_acpi_force_100khz_device_ids so that it operates at
100 kHz.
Before the change, nine touch-jump events were recorded, with additional
messages suppressed by libinput's rate limiter. With the bus forced to
100 kHz, no touch-jump events have been observed and the touchpad operates
normally.
The affected system uses BIOS X513UA.319 dated 2023-05-09.

The Qualcomm automotive SA8255p SoC relies on firmware to configure
platform resources, including clocks, interconnects and TLMM.
The driver requests resources operations over SCMI using power
and performance protocols.
The SCMI power protocol enables or disables resources like clocks,
interconnect paths, and TLMM (GPIOs) using runtime PM framework APIs,
such as resume/suspend, to control power on/off.
The SCMI performance protocol manages I2C frequency, with each
frequency rate represented by a performance level. The driver uses
geni_se_set_perf_opp() API to request the desired frequency rate..
As part of geni_se_set_perf_opp(), the OPP for the requested frequency
is obtained using dev_pm_opp_find_freq_floor() and the performance
level is set using dev_pm_opp_set_opp().
