Merge tag 'vfs-6.10.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull misc vfs updates from Christian Brauner: "This contains the usual miscellaneous features, cleanups, and fixes for vfs and individual fses. Features: - Free up FMODE_* bits. I've freed up bits 6, 7, 8, and 24. That means we now have six free FMODE_* bits in total (but bit #6 already got used for FMODE_WRITE_RESTRICTED) - Add FOP_HUGE_PAGES flag (follow-up to FMODE_* cleanup) - Add fd_raw cleanup class so we can make use of automatic cleanup provided by CLASS(fd_raw, f)(fd) for O_PATH fds as well - Optimize seq_puts() - Simplify __seq_puts() - Add new anon_inode_getfile_fmode() api to allow specifying f_mode instead of open-coding it in multiple places - Annotate struct file_handle with __counted_by() and use struct_size() - Warn in get_file() whether f_count resurrection from zero is attempted (epoll/drm discussion) - Folio-sophize aio - Export the subvolume id in statx() for both btrfs and bcachefs - Relax linkat(AT_EMPTY_PATH) requirements - Add F_DUPFD_QUERY fcntl() allowing to compare two file descriptors for dup*() equality replacing kcmp() Cleanups: - Compile out swapfile inode checks when swap isn't enabled - Use (1 << n) notation for FMODE_* bitshifts for clarity - Remove redundant variable assignment in fs/direct-io - Cleanup uses of strncpy in orangefs - Speed up and cleanup writeback - Move fsparam_string_empty() helper into header since it's currently open-coded in multiple places - Add kernel-doc comments to proc_create_net_data_write() - Don't needlessly read dentry->d_flags twice Fixes: - Fix out-of-range warning in nilfs2 - Fix ecryptfs overflow due to wrong encryption packet size calculation - Fix overly long line in xfs file_operations (follow-up to FMODE_* cleanup) - Don't raise FOP_BUFFER_{R,W}ASYNC for directories in xfs (follow-up to FMODE_* cleanup) - Don't call xfs_file_open from xfs_dir_open (follow-up to FMODE_* cleanup) - Fix stable offset api to prevent endless loops - Fix afs file server rotations - Prevent xattr node from overflowing the eraseblock in jffs2 - Move fdinfo PTRACE_MODE_READ procfs check into the .permission() operation instead of .open() operation since this caused userspace regressions" * tag 'vfs-6.10.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (39 commits) afs: Fix fileserver rotation getting stuck selftests: add F_DUPDFD_QUERY selftests fcntl: add F_DUPFD_QUERY fcntl() file: add fd_raw cleanup class fs: WARN when f_count resurrection is attempted seq_file: Simplify __seq_puts() seq_file: Optimize seq_puts() proc: Move fdinfo PTRACE_MODE_READ check into the inode .permission operation fs: Create anon_inode_getfile_fmode() xfs: don't call xfs_file_open from xfs_dir_open xfs: drop fop_flags for directories xfs: fix overly long line in the file_operations shmem: Fix shmem_rename2() libfs: Add simple_offset_rename() API libfs: Fix simple_offset_rename_exchange() jffs2: prevent xattr node from overflowing the eraseblock vfs, swap: compile out IS_SWAPFILE() on swapless configs vfs: relax linkat() AT_EMPTY_PATH - aka flink() - requirements fs/direct-io: remove redundant assignment to variable retval fs/dcache: Re-use value stored to dentry->d_flags instead of re-reading ...
