  ext4: mark inodes without acls in __ext4_iget() (2025-11-28 22:35:28 -0500)

----------------------------------------------------------------
New features and improvements for the ext4 file system

* Optimize online defragmentation by using folios instead of individual
  buffer heads
* Improve error codes stored in the superblock when the journal aborts
* Minor cleanups and clarifications in ext4_map_blocks()
* Add documentation of the casefold and encrypt flags
* Add support for file systems with a blocksize greater than the pagesize
* Improve performance by enabling the caching the fact that an inode does
  not have a Posix ACL.

Various Bug Fixes

* Fix false positive compliants from smatch
* Fix error code which is returned by ext4fs_dirhash() when Siphash is
  used without the encryption key
* Fix races when writing to inline data files which could trigger a BUG
* Fix potential NULL dereference when there is an corrupt file system with
  an extended attribute value stored in a inode
* Fix false positive lockdep report when syzbot uses ext4 and ocfs2 together
* Fix false positive reported by DEPT by adjusting lock annotation
* Avoid a potential BUG_ON in jbd2 when a file system is massively corrupted
* Fix a WARN_ON when superblock is corrupted with a non-NULL terminated
  mount options field
* Add check if the userspace passes in a non-NULL terminated mount options
  field to EXT4_IOC_SET_TUNE_SB_PARAM
* Fix a potential journal checksum failure whena file system is copied while
  it is mounted read-only
* Fix a potential potential orphan file tracking error which only showed
  on 32-bit systems
* Fix assertion checks in mballoc (which have to be explicitly enbled by
  manually enabling AGGRESSIVE_CHECKS and recompiling)
* Avoid complaining about overly large orphan files created by mke2fs with
  with file systems with a 64k block size
