Subject: [PATCH 0/5] Minor improvements and cleanups to ext4 mballoc

This series contains some minor improvements and cleanups to ext4
mballoc. No failure is found in "kvm-xfstests smoke" test and unit
test. More details can be found in respective patches. Thanks!

Kemeng Shi (5):
  ext4: keep "prefetch_grp" and "nr" consistent
  ext4: add test_mb_mark_used_cost to estimate cost of mb_mark_used
  ext4: call ext4_mb_mark_free_simple in mb_mark_used to clear bits
  ext4: use correct criteria name instead stale integer number in
    comment
  ext4: expand next_linear_group to remove repeat check for linear scan.
