Introduce super_write_guard for scoped superblock write protection. This provides a guard-based alternative to the manual sb_start_write() and sb_end_write() pattern, allowing the compiler to automatically handle the cleanup" * tag 'vfs-6.19-rc1.guards' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: xfs: use super write guard in xfs_file_ioctl() open: use super write guard in do_ftruncate() btrfs: use super write guard in relocating_repair_kthread() ext4: use super write guard in write_mmp_block() btrfs: use super write guard in sb_start_write() btrfs: use super write guard btrfs_run_defrag_inode() btrfs: use super write guard in btrfs_reclaim_bgs_work() fs: add super_write_guard 2025-12-01T22:18:01+00:00 Linus Torvalds torvalds@linux-foundation.org 2025-12-01T22:18:01+00:00 urn:sha1:afdf0fb340948a8c0f581ed1dc42828af89b80b6 Pull fs header updates from Christian Brauner: "This contains initial work to start splitting up fs.h. Begin the long-overdue work of splitting up the monolithic fs.h header. The header has grown to over 3000 lines and includes types and functions for many different subsystems, making it difficult to navigate and causing excessive compilation dependencies. This series introduces new focused headers for superblock-related code: - Rename fs_types.h to fs_dirent.h to better reflect its actual content (directory entry types) - Add fs/super_types.h containing superblock type definitions - Add fs/super.h containing superblock function declarations This is the first step in a longer effort to modularize the VFS headers. Cleanups: - Inode Field Layout Optimization (Mateusz Guzik) Move inode fields used during fast path lookup closer together to improve cache locality during path resolution. - current_umask() Optimization (Mateusz Guzik) Inline current_umask() and move it to fs_struct.h. This improves performance by avoiding function call overhead for this frequently-used function, and places it in a more appropriate header since it operates on fs_struct" * tag 'vfs-6.19-rc1.fs_header' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: fs: move inode fields used during fast path lookup closer together fs: inline current_umask() and move it to fs_struct.h fs: add fs/super.h header fs: add fs/super_types.h header fs: rename fs_types.h to fs_dirent.h 2025-11-05T21:52:15+00:00 Christian Brauner brauner@kernel.org 2025-11-04T12:12:30+00:00 urn:sha1:8e4d576ed3ff917eda65b989ba56b02d9a3894f9 Link: https://patch.msgid.link/20251104-work-guards-v1-1-5108ac78a171@kernel.org Reviewed-by: Jan Kara <jack@suse.cz> Signed-off-by: Christian Brauner <brauner@kernel.org> 2025-11-05T21:51:21+00:00 Christian Brauner brauner@kernel.org 2025-11-04T14:46:34+00:00 urn:sha1:f7b3d14165222a3ad9c4d0d31dfa81e396751801 Split out super block associated functions into a separate header.
