Linus Torvalds 83f1454877 Various ext4 updates for 7.2-rc1:
* A major rework of the fast commit mechanism to avoid lock
   contention and deadlocks.  We also export snapshot statistics
   in /proc/fs/ext4/*/fc_info.
 * Performance optimization for directory hash computation by
   processing input in 4-byte chunks and removing function pointers,
   along with new KUnit tests for directory hash.
 * Cleanups in JBD2 to remove special slabs and use kmalloc() instead.
 * Various bug fixes, including:
    - Early validation of donor superblock in EXT4_IOC_MOVE_EXT to avoid
      cross-fs deadlock
    - Fix for a kernel BUG in ext4_write_inline_data_end under
      data=journal
    - Fix for a NULL dereference in jbd2_journal_dirty_metadata when
      handle is aborted
    - Fix for an underflow in JBD2 fast commit block initialization check
    - Fix for LOGFLUSH shutdown ordering to ensure ordered data writeback
    - Miscellaneous fixes for error path return values and KUnit assertions.
