[GIT PULL] vfs fixes

[Christian Brauner <brauner@kernel.org>]

Hey Linus,

slowly resurrecting from the holidays... What year is it? And have we
already started generating pull requests with AI?

/* Summary */

This contains various fixes for this cycle:

- Relax assertions on failure to encode file handles.
  The ->encode_fh() method can fail for various reasons. None of them
  warrant a WARN_ON().

- Fix overlayfs file handle encoding by allowing encoding an fid from an
  inode without an alias.

- Make sure fuse_dir_open() handles FOPEN_KEEP_CACHE. If it's not
  specified fuse needs to invaludate the directory inode page cache.

- Fix qnx6 so it builds with gcc-15.

- Various fixes for netfslib and ceph and nfs filesystems:

  - Ignore silly rename files from afs and nfs when building header archives.

  - Fix read result collection in netfslib with multiple subrequests.

  - Handle ENOMEM for netfslib buffered reads.

  - Fix oops in nfs_netfs_init_request().

  - Parse the secctx command immediately in cachefiles.

  - Remove a redundant smp_rmb() in netfslib.

  - Handle recursion in read retry in netfslib.

  - Fix clearing of folio_queue.

  - Fix missing cancellation of copy-to_cache when the cache for a file
    is temporarly disabled in netfslib.

- Sanity check the hfs root record.

- Fix zero padding data issues in concurrent write scenarios.

- Fix is_mnt_ns_file() after converting nsfs to path_from_stashed().

- Fix missing declaration of init_files.

- Increase I/O priority when writing revoke records in jbd2.

- Flush filesystem device before updating tail sequence in jbd2.

/* Testing */

gcc version 14.2.0 (Debian 14.2.0-6)
Debian clang version 16.0.6 (27+b1)

No build failures or warnings were observed.
