  ext4: limit the number of retries after discarding preallocations blocks (2022-09-22 10:51:19 -0400)

----------------------------------------------------------------
Ext4 regression and bug fixes:

- Performance regression fix from 5.18 on a Rasberry Pi

- Fix extent parsing bug which triggers a BUG_ON when a (corrupted)
  extent tree has has a non-root node when zero entries.

- Fix a livelock where in the right (wrong) circumstances a large
  number of nfsd threads can try to write to a nearly full file
  system, and retry for hours(!)

----------------------------------------------------------------
Jan Kara (5):
      ext4: make mballoc try target group first even with mb_optimize_scan
      ext4: avoid unnecessary spreading of allocations among groups
      ext4: make directory inode spreading reflect flexbg size
      ext4: use locality group preallocation for small closed files
      ext4: use buckets for cr 1 block scan instead of rbtree

Luís Henriques (1):
      ext4: fix bug in extents parsing when eh_entries == 0 and eh_depth > 0
