Merge tag 'vfs-6.13-rc7.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs fixes from Christian Brauner:

 - 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
