Merge tag 'ext4_for_linus-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4

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

   - Fast commit performance improvements

   - Multi-fsblock atomic write support for bigalloc file systems

   - Large folio support for regular files

  This last can result in really stupendous performance for the right
  workloads. For example, see [1] where the Kernel Test Robot reported
  over 37% improvement on a large sequential I/O workload.

  There are also the usual bug fixes and cleanups. Of note are cleanups
  of the extent status tree to fix potential races that could result in
  the extent status tree getting corrupted under heavy simultaneous
  allocation and deallocation to a single file"
