Pull configfs updates from Andreas Hindborg:
- Switch the configfs rust bindings to use c string literals provided
by the compiler, rather than a macro
- A follow up on constifying `configfs_item_operations`, applying the
change to the configfs sample
* tag 'configfs-for-v7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/a.hindborg/linux:

Fix three issues in scx_userland's restart path:
- exit_req is not reset on restart, causing sched_main_loop() to exit
immediately without doing any scheduling work.
- stats_printer thread handle is local to spawn_stats_thread(), making
it impossible to join from main(). Promote it to file scope.
- The stats thread continues reading skel->bss after the skeleton is
destroyed on restart, causing a use-after-free. Join the stats thread
before destroying the skeleton to ensure it has exited.

Currently a dummy rust code is compiled to detect if the rust feature
could be enabled. It turns out that in this case rust emits a dependency
file without any external references:
/perf/feature/test-rust.d: test-rust.rs
/perf/feature/test-rust.bin: test-rust.rs
test-rust.rs:
This can lead to a situation, when rustc was removed after a successful build,
but the build process still thinks it's there and the feature is enabled on
subsequent runs.
Instead simply check the compiler presence to detect the feature, as
suggested by Arnaldo.
This way no actual test-rust.bin will be created, meaning the feature
check will not be cached and always performed. That's exactly what we
want, and the overhead of doing this every time is minimal.
Tested with multiple rounds of install/remove of the rust package.

eng_id can be negative and that stream_enc_regs[]
can be indexed out of bounds.
eng_id is used directly as an index into stream_enc_regs[], which has
only 5 entries. When eng_id is 5 (ENGINE_ID_DIGF) or negative, this can
access memory past the end of the array.
Add a bounds check using ARRAY_SIZE() before using eng_id as an index.
The unsigned cast also rejects negative values.
This avoids out-of-bounds access.
Fixes the below smatch error:
dcn*_resource.c: stream_encoder_create() may index
stream_enc_regs[eng_id] out of bounds (size 5).

After commit 1ef15fbe67 ("cifs: client: enforce consistent handling
of multichannel and max_channels"), invalid mount options started to
be ignored, allowing cifs.ko to proceed with the mount instead of
baling out.
The problem was related to smb3_handle_conflicting_options() being
called even when an invalid parameter had been parsed, overwriting the
return value of vfs_parse_fs_string() in
smb3_fs_context_parse_monolithic().
Fix this by calling smb3_handle_conflicting_options() only when a
valid mount option has been passed.

$ mount.cifs //srv/share /mnt -o ${opts}

Invalidating a dmabuf will impact other users of the shared BO.
In the scenario where process A moves the BO, it needs to inform
process B about the move and process B will need to update its
page table.
The commit fixes a synchronisation bug caused by the use of the
ticket: it made amdgpu_vm_handle_moved behave as if updating
the page table immediately was correct but in this case it's not.
An example is the following scenario, with 2 GPUs and glxgears
running on GPU0 and Xorg running on GPU1, on a system where P2P
PCI isn't supported:
glxgears:
export linear buffer from GPU0 and import using GPU1
submit frame rendering to GPU0
submit tiled->linear blit
Xorg:
copy of linear buffer
The sequence of jobs would be:
drm_sched_job_run # GPU0, frame rendering
drm_sched_job_queue # GPU0, blit
drm_sched_job_done # GPU0, frame rendering
drm_sched_job_run # GPU0, blit
move linear buffer for GPU1 access #
amdgpu_dma_buf_move_notify -> update pt # GPU0
It this point the blit job on GPU0 is still running and would
likely produce a page fault.

Send unload command to smu during modprobe -r amdgpu for smu 13/14.
1. This can fix the high voltage/temperatue issue after driver is unloaded.
2. Reloading driver could fail but with the debug port based mode1 reset
during driver is reloaded, it is good and safe.

Currently DCE doesn't support the overlay cursor, so the
dm_crtc_get_cursor_mode() function returns DM_CURSOR_NATIVE_MODE
unconditionally. The outcome is that it doesn't check for the
conditions that would necessitate the overlay cursor, meaning
that it doesn't reject cases where the native cursor mode isn't
supported on DCE.
Remove the early return from dm_crtc_get_cursor_mode() for
DCE and instead let it perform the necessary checks and
return DM_CURSOR_OVERLAY_MODE. Add a later check that rejects
when DM_CURSOR_OVERLAY_MODE would be used with DCE.
Fixes: 1b04dcca4f ("drm/amd/display: Introduce overlay cursor mode")

The driver uses strncmp() to compare sysfs attribute strings,
which does not handle trailing newlines and lacks NULL safety.
sysfs_streq() is the recommended function for sysfs string equality
checks in the kernel, providing safer and more correct behavior.
replace strncmp() with sysfs_streq() in drivers/gpu/drm/amd/pm/amdgpu_pm.c
