The vfs.file branch merged into here has also been merged into io_uring which depends on it. Features ======== * Add Jan Kara as VFS reviewer. * Show correct device and inode numbers in proc//maps for vma files on stacked filesystems. This is now easily doable thanks to the backing file work from the last cycles. This comes with selftests. Cleanups ======== * Remove a redundant might_sleep() from wait_on_inode(). * Initialize pointer with NULL, not 0. * Clarify comment on access_override_creds(). * Rework and simplify eventfd_signal() and eventfd_signal_mask() helpers. * Process aio completions in batches to avoid needless wakeups. * Completely decouple struct mnt_idmap from namespaces. We now only keep the actual idmapping around and don't stash references to namespaces. * Reformat maintainer entries to indicate that a given subsystem belongs to fs/. * Simplify fput() for files that were never opened. * Get rid of various pointless file helpers. * Rename various file helpers. * Rename struct file members after SLAB_TYPESAFE_BY_RCU switch from last cycle. * Make relatime_need_update() return bool. * Use GFP_KERNEL instead of GFP_USER when allocating superblocks. * Replace deprecated ida_simple_*() calls with their current ida_*() counterparts. Fixes ===== * Fix comments on user namespace id mapping helpers. They aren't kernel doc comments so they shouldn't be using /**. * s/Retuns/Returns/g in various places. * Add missing parameter documentation on can_move_mount_beneath(). * Rename i_mapping->private_data to i_mapping->i_private_data. * Fix a false-positive lockdep warning in pipe_write() for watch queues. * Improve __fget_files_rcu() code generation to improve performance. * Only notify writer that pipe resizing has finished after setting pipe->max_usage otherwise writers are never notified that the pipe has been resized and hang. * Fix some kernel docs in hfsplus. * s/passs/pass/g in various places. * Fix kernel docs in ntfs. * Fix kcalloc() arguments order reported by gcc 14. * Fix uninitialized value in reiserfs. /* Testing */ clang: Debian clang version 16.0.6 (19) gcc: (Debian 13.2.0-7) 13.2.0 All patches are based on v6.7-rc1 and have been sitting in linux-next. No build failures or warnings were observed. /* Conflicts */ Merge conflicts with other trees ================================ [1] linux-next: manual merge of the vfs-brauner tree with the mm tree https://lore.kernel.org/linux-next/20231122103119.34d23955@canb.auug.org.au [2] linux-next: manual merge of the vfs-brauner tree with the btrfs tree https://lore.kernel.org/linux-next/20231127091437.4062f96c@canb.auug.org.au The following changes since commit b85ea95d086471afb4ad062012a4d73cd328fa86: Linux 6.7-rc1 (2023-11-12 16:19:07 -0800) are available in the Git repository at: git@gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs tags/vfs-6.8.misc for you to fetch changes up to dd8f87f21dc3da2eaf46e7401173f935b90b13a8: reiserfs: fix uninit-value in comp_keys (2023-12-28 11:56:52 +0100) Please consider pulling these changes from the signed vfs-6.8.misc tag.
