2026-02-16io_uring/bpf_filter: pass in expected filter payload sizeJens Axboe
It's quite possible that opcodes that have payloads attached to them, like IORING_OP_OPENAT/OPENAT2 or IORING_OP_SOCKET, that these paylods can change over time. For example, on the openat/openat2 side, the struct open_how argument is extensible, and could be extended in the future to allow further arguments to be passed in. Allow registration of a cBPF filter to give the size of the filter as seen by userspace. If that filter is for an opcode that takes extra payload data, allow it if the application payload expectation is the same size than the kernels. If that is the case, the kernel supports filtering on the payload that the application expects. If the size differs, the behavior depends on the IO_URING_BPF_FILTER_SZ_STRICT flag: 1) If IO_URING_BPF_FILTER_SZ_STRICT is set and the size expectation differs, fail the attempt to load the filter. 2) If IO_URING_BPF_FILTER_SZ_STRICT isn't set, allow the filter if the userspace pdu size is smaller than what the kernel offers. 3) Regardless if IO_URING_BPF_FILTER_SZ_STRICT, fail loading the filter if the userspace pdu size is bigger than what the kernel supports. An attempt to load a filter due to sizing will error with -EMSGSIZE. For that error, the registration struct will have filter->pdu_size populated with the pdu size that the kernel uses.

2026-02-16io_uring/bpf_filter: move filter size and populate helper into structJens Axboe
Rather than open-code this logic in io_uring_populate_bpf_ctx() with a switch, move it to the issue side definitions. Outside of making this easier to extend in the future, it's also a prep patch for using the pdu size for a given opcode filter elsewhere. Signed-off-by: Jens Axboe <axboe@kernel.dk>

2026-02-16io_uring/cancel: de-unionize file and user_data in struct io_cancel_dataJens Axboe
By having them share the same space in struct io_cancel_data, it ends up disallowing IORING_ASYNC_CANCEL_FD|IORING_ASYNC_CANCEL_USERDATA from working. Eg you cannot match on both a file and user_data for cancelation purposes. This obviously isn't a common use case as nobody has reported this, but it does result in -ENOENT potentially being returned when trying to match on both, rather than actually doing what the API says it would.

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull more misc vfs updates from Christian Brauner: "Features: - Optimize close_range() from O(range size) to O(active FDs) by using find_next_bit() on the open_fds bitmap instead of linearly scanning the entire requested range. This is a significant improvement for large-range close operations on sparse file descriptor tables. - Add FS_XFLAG_VERITY file attribute for fs-verity files, retrievable via FS_IOC_FSGETXATTR and file_getattr(). The flag is read-only. Add tracepoints for fs-verity enable and verify operations, replacing the previously removed debug printk's. - Prevent nfsd from exporting special kernel filesystems like pidfs and nsfs. These filesystems have custom ->open() and ->permission() export methods that are designed for open_by_handle_at(2) only and are incompatible with nfsd. Update the exportfs documentation accordingly. Fixes: - Fix KMSAN uninit-value in ovl_fill_real() where strcmp() was used on a non-null-terminated decrypted directory entry name from fscrypt. This triggered on encrypted lower layers when the decrypted name buffer contained uninitialized tail data. The fix also adds VFS-level name_is_dot(), name_is_dotdot(), and name_is_dot_dotdot() helpers, replacing various open-coded "." and ".." checks across the tree. - Fix read-only fsflags not being reset together with xflags in vfs_fileattr_set(). Currently harmless since no read-only xflags overlap with flags, but this would cause inconsistencies for any future shared read-only flag - Return -EREMOTE instead of -ESRCH from PIDFD_GET_INFO when the target process is in a different pid namespace. This lets userspace distinguish "process exited" from "process in another namespace", matching glibc's pidfd_getpid() behavior Cleanups: - Use C-string literals in the Rust seq_file bindings, replacing the kernel::c_str!() macro (available since Rust 1.77) - Fix typo in d_walk_ret enum comment, add porting notes for the readlink_copy() calling convention change" * tag 'vfs-7.0-rc1.misc.2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: fs: add porting notes about readlink_copy() pidfs: return -EREMOTE when PIDFD_GET_INFO is called on another ns nfsd: do not allow exporting of special kernel filesystems exportfs: clarify the documentation of open()/permission() expotrfs ops fsverity: add tracepoints fs: add FS_XFLAG_VERITY for fs-verity files rust: seq_file: replace `kernel::c_str!` with C-Strings fs: dcache: fix typo in enum d_walk_ret comment ovl: use name_is_dot* helpers in readdir code fs: add helpers name_is_dot{,dot,_dotdot} ovl: Fix uninit-value in ovl_fill_real fs: reset read-only fsflags together with xflags fs/file: optimize close_range() complexity from O(N) to O(Sparse)

2026-02-16blk-mq: use NOIO context to prevent deadlock during debugfs creationYu Kuai
Creating debugfs entries can trigger fs reclaim, which can enter back into the block layer request_queue. This can cause deadlock if the queue is frozen. Previously, a WARN_ON_ONCE check was used in debugfs_create_files() to detect this condition, but it was racy since the queue can be frozen from another context at any time. Introduce blk_debugfs_lock()/blk_debugfs_unlock() helpers that combine the debugfs_mutex with memalloc_noio_save()/restore() to prevent fs reclaim from triggering block I/O. Also add blk_debugfs_lock_nomemsave() and blk_debugfs_unlock_nomemrestore() variants for callers that don't need NOIO protection (e.g., debugfs removal or read-only operations). Replace all raw debugfs_mutex lock/unlock pairs with these helpers, using the _nomemsave/_nomemrestore variants where appropriate.

2026-02-16ACPI: PM: Add unused power resource quirk for THUNDEROBOT ZEROZhai Can
On the THUNDEROBOT ZERO laptop, the second NVMe slot and the discrete NVIDIA GPU are both controlled by power-resource PXP. Due to the SSDT table bug (lack of reference), PXP will be shut dow as an "unused" power resource during initialization, making the NVMe slot #2 + NVIDIA both inaccessible. This issue was introduced by commit a1224f34d72a ("ACPI: PM: Check states of power resources during initialization"). Here are test results on the three consecutive commits: (bad again!) a1224f34d72a ACPI: PM: Check states of power resources during initialization (good) bc2836859643 ACPI: PM: Do not turn off power resources in unknown state (bad) 519d81956ee2 Linux 5.15-rc6 On commit bc2836859643 ("ACPI: PM: Do not turn off power resources in unknown state") this was not an issue because the power resource state left UNKNOWN thus being ignored. See also commit 9b04d99788cf ("ACPI: PM: Do not turn of unused power resources on the Toshiba Click Mini") which is another almost identical case to this one.

2026-02-16regulator: s2mps11: drop redundant sanity checks in s2mpg10_of_parse_cb()André Draszik
The sanity checks being removed in this commit are useless as earlier code already checks for all conditions, including all error cases like out-of-bounds conditions. In other words, the code being removed here has no effect, as any potential error it could catch will already have been caught by earlier code. The checks removed here are also incomplete (as they're off-by-one) - they should have been checking >= ARRAY_SIZE() to be complete. Simply remove this redundant and incorrect code. No functional change.

2026-02-16fs/ntfs3: add delayed-allocation (delalloc) supportKonstantin Komarov
This patch implements delayed allocation (delalloc) in ntfs3 driver. It introduces an in-memory delayed-runlist (run_da) and the helpers to track, reserve and later convert those delayed reservations into real clusters at writeback time. The change keeps on-disk formats untouched and focuses on pagecache integration, correctness and safe interaction with fallocate, truncate, and dio/iomap paths. Key points: - add run_da (delay-allocated run tree) and bookkeeping for delayed clusters. - mark ranges as delalloc (DELALLOC_LCN) instead of immediately allocating. Actual allocation performed later (writeback / attr_set_size_ex / explicit flush paths). - direct i/o / iomap paths updated to avoid dio collisions with delalloc: dio falls back or forces allocation of delayed blocks before proceeding. - punch/collapse/truncate/fallocate check and cancel delay-alloc reservations. Sparse/compressed files handled specially. - free-space checks updated (ntfs_check_free_space) to account for reserved delalloc clusters and MFT record budgeting. - delayed allocations are committed on last writer (file release) and on explicit allocation flush paths.

2026-02-16io_uring/cmd_net: fix too strict requirement on ioctlAsbjørn Sloth Tønnesen
Attempting SOCKET_URING_OP_SETSOCKOPT on an AF_NETLINK socket resulted in an -EOPNOTSUPP, as AF_NETLINK doesn't have an ioctl in its struct proto, but only in struct proto_ops. Prior to the blamed commit, io_uring_cmd_sock() only had two cmd_op operations, both requiring ioctl, thus the check was warranted. Since then, 4 new cmd_op operations have been added, none of which depend on ioctl. This patch moves the ioctl check, so it only applies to the original operations. AFAICT, the ioctl requirement was unintentional, and it wasn't visible in the blamed patch within 3 lines of context.

2026-02-16ALSA: usb-audio: Add sanity check for OOB writes at silencingTakashi Iwai
At silencing the playback URB packets in the implicit fb mode before the actual playback, we blindly assume that the received packets fit with the buffer size. But when the setup in the capture stream differs from the playback stream (e.g. due to the USB core limitation of max packet size), such an inconsistency may lead to OOB writes to the buffer, resulting in a crash. For addressing it, add a sanity check of the transfer buffer size at prepare_silent_urb(), and stop the data copy if the received data overflows. Also, report back the transfer error properly from there, too. Note that this doesn't fix the root cause of the playback error itself, but this merely covers the kernel Oops.

2026-02-14io_uring/zcrx: fix sgtable leak on mapping failuresPavel Begunkov
In an unlikely case when io_populate_area_dma() fails, which could only happen on a PAGE_POOL_32BIT_ARCH_WITH_64BIT_DMA machine, io_zcrx_map_area() will have an initialised and not freed table. It was supposed to be cleaned up in the error path, but !is_mapped prevents that.
