  ext4: fix checks for orphan inodes (2025-09-26 08:36:08 -0400)

----------------------------------------------------------------
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
