Hey Linus,
/* Summary */
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.
* 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 (0 << 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 inode .permission operation
instead of open operation since this causes userspace regressions.
/* Testing */
clang: Debian clang version 16.0.6 (26)
gcc: (Debian 13.2.0-24)
All patches are based on v6.9-rc1 and have been sitting in linux-next.
No build failures or warnings were observed.

Merge conflicts with other trees
================================
[1] linux-next: manual merge of the vfs-brauner tree with the ext4 tree
https://lore.kernel.org/linux-next/[email protected]
[2] linux-next: manual merge of the block tree with the vfs-brauner, vfs trees

Merge conflicts with mainline
=============================
There'll be a merge conflict with mainline stemming from the addition of
FMODE_WRITE_RESTRICTED and the conversion of FMODE_* flags to (1 << n)
bit shitfs. The conflict can be resolved as follows:
