2026-02-19HID: Document memory allocation properties of report_fixup()Günther Noack1-0/+6
The memory pointer returned by the report_fixup() hook does not get freed by the caller. Instead, report_fixup() must return (in return value and *rsize) a memory buffer with at least the same lifetime as the input buffer (defined by rdesc and original *rsize). This is usually achieved using one of the following techniques: * Returning a pointer and size to a sub-portion of the input buffer * Returning a pointer to a static buffer * Allocating a buffer with a devm_*() function, which will automatically get freed when the device is removed.

2026-02-19net/mlx5: Fix multiport device check over light SFsShay Drory1-2/+2
Driver is using num_vhca_ports capability to distinguish between multiport master device and multiport slave device. num_vhca_ports is a capability the driver sets according to the MAX num_vhca_ports capability reported by FW. On the other hand, light SFs doesn't set the above capbility. This leads to wrong results whenever light SFs is checking whether he is a multiport master or slave. Therefore, use the MAX capability to distinguish between master and slave devices.

2026-02-19fs: add generic FS_IOC_SHUTDOWN definitionsNamjae Jeon1-0/+12
Currently, several filesystems (e.g., xfs, ext4, btrfs) implement a "shutdown" or "going down" ioctl to simulate filesystem force a shutdown. While they often use the same underlying numeric value, the definition is duplicated across filesystem headers or private definitions. Add generic definitions for FS_IOC_SHUTDOWN in uapi/linux/fs.h. This allows new filesystems (like ntfs) to implement this feature using a standard VFS definition and paves the way for existing filesystems to unify their definitions later. The flag names are standardized as FS_SHUTDOWN_* to be consistent with the ioctl name, replacing the historical GOING_DOWN naming convention. Reviewed-by: "Darrick J.

2026-02-19mshv: Add support for integrated schedulerStanislav Kinsburskii1-1/+6
Query the hypervisor for integrated scheduler support and use it if configured. Microsoft Hypervisor originally provided two schedulers: root and core. The root scheduler allows the root partition to schedule guest vCPUs across physical cores, supporting both time slicing and CPU affinity (e.g., via cgroups). In contrast, the core scheduler delegates vCPU-to-physical-core scheduling entirely to the hypervisor. Direct virtualization introduces a new privileged guest partition type - L1 Virtual Host (L1VH) — which can create child partitions from its own resources. These child partitions are effectively siblings, scheduled by the hypervisor's core scheduler. This prevents the L1VH parent from setting affinity or time slicing for its own processes or guest VPs. While cgroups, CFS, and cpuset controllers can still be used, their effectiveness is unpredictable, as the core scheduler swaps vCPUs according to its own logic (typically round-robin across all allocated physical CPUs). As a result, the system may appear to "steal" time from the L1VH and its children. To address this, Microsoft Hypervisor introduces the integrated scheduler. This allows an L1VH partition to schedule its own vCPUs and those of its guests across its "physical" cores, effectively emulating root scheduler behavior within the L1VH, while retaining core scheduler behavior for the rest of the system. The integrated scheduler is controlled by the root partition and gated by the vmm_enable_integrated_scheduler capability bit. If set, the hypervisor supports the integrated scheduler. The L1VH partition must then check if it is enabled by querying the corresponding extended partition property. If this property is true, the L1VH partition must use the root scheduler logic; otherwise, it must use the core scheduler. This requirement makes reading VMM capabilities in L1VH partition a requirement too.

2026-02-17drm/pagemap: pass pagemap_addr by referenceArnd Bergmann1-1/+1
Passing a structure by value into a function is sometimes problematic, for a number of reasons. Of of these is a warning from the 32-bit arm compiler: drivers/gpu/drm/drm_gpusvm.c: In function '__drm_gpusvm_unmap_pages': drivers/gpu/drm/drm_gpusvm.c:1152:33: note: parameter passing for argument of type 'struct drm_pagemap_addr' changed in GCC 9.1 1152 | dpagemap->ops->device_unmap(dpagemap, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1153 | dev, *addr); | ~~~~~~~~~~~ This particular problem is harmless since we are not mixing compiler versions inside of the compiler. However, passing this by reference avoids the warning along with providing slightly better calling conventions as it avoids an extra copy on the stack.

2026-02-17io_uring/bpf_filter: pass in expected filter payload sizeJens Axboe1-1/+7
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.

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)
