drm/i915/color: Create a transfer function color pipeline
Add a color pipeline with three colorops in the sequence
1D LUT - 3x4 CTM - 1D LUT
This pipeline can be used to do any color space conversion or HDR
tone mapping
v2: Change namespace to drm_plane_colorop*
v3: Use simpler/pre-existing colorops for first iteration
v4:
- s/*_tf_*/*_color_* (Jani)
- Refactor to separate files (Jani)
- Add missing space in comment (Suraj)
- Consolidate patch that adds/attaches pipeline property
v5:
- Limit MAX_COLOR_PIPELINES to 2.(Suraj)
Increase it as and when we add more pipelines.
- Remove redundant initialization code (Suraj)
v6:
- Use drm_plane_create_color_pipeline_property() (Arun)
Now MAX_COLOR_PIPELINES is 1

mm/mm_init: Introduce a boot parameter for check_pages
Use-after-free and double-free bugs can be very difficult to track down.
The kernel is good at tracking these and preventing bad pages from being
used/created through simple checks gated behind "check_pages_enabled".
Currently, the only ways to enable this flag is by building with
CONFIG_DEBUG_VM, or as a side effect of other checks such as
init_on_{alloc, free}, page_poisoning, or debug_pagealloc among others.
These solutions are powerful, but may often be too coarse in balancing
the performance vs. safety that a user may want, particularly in
latency-sensitive production environments.
Introduce a new boot parameter "check_pages", which enables page checking
with no other side effects. It takes kstrbool-able inputs as an argument
(i.e. 0/1, true/false, on/off, ...). This patch is backwards-compatible;
setting CONFIG_DEBUG_VM still enables page checking.

drm/panel: novatek-nt35560: avoid on-stack device structure
A cleanup patch apparently by accident used a local device structure
instead of a pointer to one in the nt35560_read_id() function, causing
a warning about stack usage:
drivers/gpu/drm/panel/panel-novatek-nt35560.c: In function 'nt35560_read_id':
drivers/gpu/drm/panel/panel-novatek-nt35560.c:249:1: error: the frame size of 1296 bytes is larger than 1280 bytes [-Werror=frame-larger-than=]
Change this to a pointer as was liley intended here.

Merge tag 'drm-next-2025-12-03' of https://gitlab.freedesktop.org/drm/kernel
Pull drm updates from Dave Airlie:
"There was a rather late merge of a new color pipeline feature, that
some userspace projects are blocked on, and has seen a lot of work in
amdgpu. This should have seen some time in -next. There is additional
support for this for Intel, that if it arrives in the next day or two
I'll pass it on in another pull request and you can decide if you want
to take it.
Highlights:
- Arm Ethos NPU accelerator driver
- new DRM color pipeline support
- amdgpu will now run discrete SI/CIK cards instead of radeon, which
enables vulkan support in userspace
- msm gets gen8 gpu support
- initial Xe3P support in xe

blk-mq: Abort suspend when wakeup events are pending
During system suspend, wakeup capable IRQs for block device can be
delayed, which can cause blk_mq_hctx_notify_offline() to hang
indefinitely while waiting for pending request to complete.
Skip the request waiting loop and abort suspend when wakeup events are
pending to prevent the deadlock.

blk-mq: add blk_rq_nr_bvec() helper
Add a new helper function blk_rq_nr_bvec() that returns the number of bvecs in a request. This count represents the number of iterations rq_for_each_bvec() would perform on a request. Drivers need to pre-allocate bvec arrays before iterating through a request's bvecs. Currently, they manually count bvecs using rq_for_each_bvec() in a loop, which is repetitive. The new helper centralizes this logic. This pattern exists in loop and zloop drivers, where multi-bio requests require copying bvecs into a contiguous array before creating an iov_iter for file operations. Update loop and zloop drivers to use the new helper, eliminating duplicate code. This patch also provides a clear API to avoid any potential misuse of blk_nr_phys_segments() for calculating the bvecs since, one bvec can have more than one segments and use of blk_nr_phys_segments() can lead to extra memory allocation :- [ 6155.673749] nullb_bio: 128K bio as ONE bvec: sector=0, size=131072 [ 6155.673846] null_blk: #### null_handle_data_transfer:1375 [ 6155.673850] null_blk: nr_bvec=1 blk_rq_nr_phys_segments=2 [ 6155.674263] null_blk: #### null_handle_data_transfer:1375 [ 6155.674267] null_blk: nr_bvec=1 blk_rq_nr_phys_segments=1 Reviewed-by: Niklas Cassel <cassel@kernel.org> Signed-off-by: Chaitanya Kulkarni <ckulkarnilinux@gmail.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk> |

io_uring/io-wq: always retry worker create on ERESTART*
If a task has a pending signal when create_io_thread() is called,
copy_process() will return -ERESTARTNOINTR. io_should_retry_thread()
will request a retry of create_io_thread() up to WORKER_INIT_LIMIT = 3
times. If all retries fail, the io_uring request will fail with
ECANCELED.
Commit 3918315c5dc ("io-wq: backoff when retrying worker creation")
added a linear backoff to allow the thread to handle its signal before
the retry. However, a thread receiving frequent signals may get unlucky
and have a signal pending at every retry. Since the userspace task
doesn't control when it receives signals, there's no easy way for it to
prevent the create_io_thread() failure due to pending signals. The task
may also lack the information necessary to regenerate the canceled SQE.
So always retry the create_io_thread() on the ERESTART* errors,
analogous to what a fork() syscall would do. EAGAIN can occur due to
various persistent conditions such as exceeding RLIMIT_NPROC, so respect
the WORKER_INIT_LIMIT retry limit for EAGAIN errors.

io_uring/poll: correctly handle io_poll_add() return value on update
When the core of io_uring was updated to handle completions
consistently and with fixed return codes, the POLL_REMOVE opcode
with updates got slightly broken. If a POLL_ADD is pending and
then POLL_REMOVE is used to update the events of that request, if that
update causes the POLL_ADD to now trigger, then that completion is lost
and a CQE is never posted.
Additionally, ensure that if an update does cause an existing POLL_ADD
to complete, that the completion value isn't always overwritten with
-ECANCELED. For that case, whatever io_poll_add() set the value to
should just be retained.

autofs: fix per-dentry timeout warning
The check that determines if the message that warns about the per-dentry timeout being greater than the super block timeout is not correct. The initial value for this field is -1 and the type of the field is unsigned long. I could change the type to long but the message is in the wrong place too, it should come after the timeout setting. So leave everything else as it is and move the message and check the timeout is actually set as an additional condition on issuing the message. Also fix the timeout comparison.

cifs: client: enforce consistent handling of multichannel and max_channels
Previously, the behavior of the multichannel and max_channels mount options was inconsistent and order-dependent. For example, specifying "multichannel,max_channels=1" would result in 2 channels, while "max_channels=1,multichannel" would result in 1 channel. Additionally, conflicting combinations such as "nomultichannel,max_channels=3" or "multichannel,max_channels=1" did not produce errors and could lead to unexpected channel counts. This commit introduces two new fields in smb3_fs_context to explicitly track whether multichannel and max_channels were specified during mount. The option parsing and validation logic is updated to ensure: - The outcome is no longer dependent on the order of options. - Conflicting combinations (e.g., "nomultichannel,max_channels=3" or "multichannel,max_channels=1") are detected and result in an error. - The number of channels created is consistent with the specified options. This improves the reliability and predictability of mount option handling for SMB3 multichannel support.

New features and improvements for the ext4 file system
* Optimize online defragmentation by using folios instead of individual
buffer heads
* Improve error codes stored in the superblock when the journal aborts
* Minor cleanups and clarifications in ext4_map_blocks()
* Add documentation of the casefold and encrypt flags
* Add support for file systems with a blocksize greater than the pagesize
* Improve performance by enabling the caching the fact that an inode does
not have a Posix ACL.
Various Bug Fixes
* Fix false positive compliants from smatch
* Fix error code which is returned by ext4fs_dirhash() when Siphash is
used without the encryption key
* Fix races when writing to inline data files which could trigger a BUG
* Fix potential NULL dereference when there is an corrupt file system with
an extended attribute value stored in a inode
* Fix false positive lockdep report when syzbot uses ext4 and ocfs2 together
* Fix false positive reported by DEPT by adjusting lock annotation
* Avoid a potential BUG_ON in jbd2 when a file system is massively corrupted
* Fix a WARN_ON when superblock is corrupted with a non-NULL terminated
mount options field
* Add check if the userspace passes in a non-NULL terminated mount options
field to EXT4_IOC_SET_TUNE_SB_PARAM
* Fix a potential journal checksum failure whena file system is copied while
it is mounted read-only
* Fix a potential potential orphan file tracking error which only showed
on 32-bit systems
* Fix assertion checks in mballoc (which have to be explicitly enbled by
manually enabling AGGRESSIVE_CHECKS and recompiling)
* Avoid complaining about overly large orphan files created by mke2fs with
with file systems with a 64k block size

"Several fixes for syzbot reported issues, HFS/HFS+ fixes of xfstests
failures, Kunit-based unit-tests introduction, and code cleanup:
- Dan Carpenter fixed a potential use-after-free issue in
hfs_correct_next_unused_CNID() method. Tetsuo Handa has made nice
fix of syzbot reported issue related to incorrect inode->i_mode
management if volume has been corrupted somehow. Yang Chenzhi has
made really good fix of potential race condition in
__hfs_bnode_create() method for HFS+ file system.
- Several fixes to xfstests failures. Particularly, generic/070,
generic/073, and generic/101 test-cases finish successfully for the
case of HFS+ file system right now.
- HFS and HFS+ drivers share multiple structures of on-disk layout
declarations. Some structures are used without any change. However,
we had two independent declarations of the same structures in HFS
and HFS+ drivers.
The on-disk layout declarations have been moved into
include/linux/hfs_common.h with the goal to exclude the
declarations duplication and to keep the HFS/HFS+ on-disk layout
declarations in one place.
Also, this patch prepares the basis for creating a hfslib that can
aggregate common functionality without necessity to duplicate the
same code in HFS and HFS+ drivers.
- HFS/HFS+ really need unit-tests because of multiple xfstests
failures. The first two patches introduce Kunit-based unit-tests
for the case string operations in HFS/HFS+ file system drivers"

Pull btrfs updates from David Sterba:
"Features:
- shutdown ioctl support (needs CONFIG_BTRFS_EXPERIMENTAL for now):
- set filesystem state as being shut down (also named going down
in other filesystems), where all active operations return EIO
and this cannot be changed until unmount
- pending operations are attempted to be finished but error
messages may still show up depending on where exactly the
shutdown happened
- scrub (and device replace) vs suspend/hibernate:
- a running scrub will prevent suspend, which can be annoying as
suspend is an immediate request and scrub is not critical
- filesystem freezing before suspend was not sufficient as the
problem was in process freezing
- behaviour change: on suspend scrub and device replace are
cancelled, where scrub can record the last state and continue
from there; the device replace has to be restarted from the
beginning
- zone stats exported in sysfs, from the perspective of the
filesystem this includes active, reclaimable, relocation etc zones
Performance:
- improvements when processing space reservation tickets by
optimizing locking and shrinking critical sections, cumulative
improvements in lockstat numbers show +15%
Notable fixes:
- use vmalloc fallback when allocating bios as high order allocations
can happen with wide checksums (like sha256)
- scrub will always track the last position of progress so it's not
starting from zero after an error
Core:
- under experimental config, checksum calculations are offloaded to
process context, simplifies locking and allows to remove
compression write worker kthread(s):
- speed improvement in direct IO throughput with buffered IO
fallback is +15% when not offloaded but this is more related to
internal crypto subsystem improvements
- this will be probably default in the future removing the sysfs
tunable
- (experimental) block size > page size updates:
- support more operations when not using large folios (encoded
read/write and send)
- raid56
- more preparations for fscrypt support
Other:
- more conversions to auto-cleaned variables
- parameter cleanups and removals
- extended warning fixes
- improved printing of structured values like keys
- lots of other cleanups and refactoring"

This adds similar support for SQEs, where the occasional need for a 128b SQE doesn't necessitate having all SQEs be 128b in size - Introduce zcrx and SQ/CQ layout queries. The former returns what zcrx features are available. And both return the ring size information to help with allocation size calculation for user provided rings like IORING_SETUP_NO_MMAP and IORING_MEM_REGION_TYPE_USER - Zcrx updates for 6.19. It includes a bunch of small patches, IORING_REGISTER_ZCRX_CTRL and RQ flushing and David's work on sharing zcrx b/w multiple io_uring instances - Series cleaning up ring initializations, notable deduplicating ring size and offset calculations. It also moves most of the checking before doing any allocations, making the code simpler - Add support for getsockname and getpeername, which is mostly a trivial hookup after a bit of refactoring on the networking side - Various fixes and cleanups * tag 'for-6.19/io_uring-20251201' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: (68 commits) io_uring: Introduce getsockname io_uring cmd socket: Split out a getsockname helper for io_uring socket: Unify getsockname and getpeername implementation io_uring/query: drop unused io_handle_query_entry() ctx arg io_uring/kbuf: remove obsolete buf_nr_pages and update comments io_uring/register: use correct location for io_rings_layout io_uring/zcrx: share an ifq between rings io_uring/zcrx: add io_fill_zcrx_offsets() io_uring/zcrx: export zcrx via a file io_uring/zcrx: move io_zcrx_scrub() and dependencies up io_uring/zcrx: count zcrx users io_uring/zcrx: add sync refill queue flushing io_uring/zcrx: introduce IORING_REGISTER_ZCRX_CTRL io_uring/zcrx: elide passing msg flags io_uring/zcrx: use folio_nr_pages() instead of shift operation io_uring/zcrx: convert to use netmem_desc io_uring/query: introduce rings info query io_uring/query: introduce zcrx query io_uring: move cq/sq user offset init around io_uring: pre-calculate scq layout ... |

f2fs: ignore discard return value
__blkdev_issue_discard() always returns 0, making the error assignment in __submit_discard_cmd() dead code. Initialize err to 0 and remove the error assignment from the __blkdev_issue_discard() call to err. Move fault injection code into already present if branch where err is set to -EIO. This preserves the fault injection behavior while removing dead error handling. Reviewed-by: Martin K.

f2fs: optimize trace_f2fs_write_checkpoint with enums
This patch optimizes the tracepoint by replacing these hardcoded strings with a new enumeration f2fs_cp_phase. 1.Defines enum f2fs_cp_phase with values for each checkpoint phase. 2.Updates trace_f2fs_write_checkpoint to accept a u16 phase argument instead of a string pointer. 3.Uses __print_symbolic in TP_printk to convert the enum values back to their corresponding strings for human-readable trace output. This change reduces the storage overhead for each trace event by replacing a variable-length string with a 2-byte integer, while maintaining the same readable output in ftrace.

f2fs: fix to not account invalid blocks in get_left_section_blocks()
w/ LFS mode, in get_left_section_blocks(), we should not account the blocks which were used before and now are invalided, otherwise those blocks will be counted as freed one in has_curseg_enough_space(), result in missing to trigger GC in time. Cc: stable@kernel.org Fixes: |

docs: f2fs: wrap ASCII tables in literal blocks to fix LaTeX build
Sphinx's LaTeX builder fails when converting the nested ASCII tables in f2fs.rst, producing the following error: "Markup is unsupported in LaTeX: longtable does not support nesting a table." Wrap the affected ASCII tables in literal code blocks to force Sphinx to render them verbatim. This prevents nested longtables and fixes the PDF build failure on Sphinx 8.2.x.

f2fs: change default schedule timeout value
This patch changes default schedule timeout value from 20ms to 1ms, in order to give caller more chances to check whether IO or non-IO congestion condition has already been mitigable.
