Merge tag 'ext4_for_linus-6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4

Pull ext4 updates from Ted Ts'o:
 "New ext4 features:

   - Add support so tune2fs can modify/update the superblock using an
     ioctl, without needing write access to the block device

   - Add support for 32-bit reserved uid's and gid's

  Bug fixes:

   - Fix potential warnings and other failures caused by corrupted /
     fuzzed file systems

   - Fail unaligned direct I/O write with EINVAL instead of silently
     falling back to buffered I/O

   - Correectly handle fsmap queries for metadata mappings

   - Avoid journal stalls caused by writeback throttling

   - Add some missing GFP_NOFAIL flags to avoid potential deadlocks
     under extremem memory pressure

  Cleanups:

   - Remove obsolete EXT3 Kconfigs"
