Baokun Li c9b528c357 ext4: regenerate buddy after block freeing failed if under fc replay ... This mostly reverts commit 6bd97bf273 ("ext4: remove redundant mb_regenerate_buddy()") and reintroduces mb_regenerate_buddy(). Based on code in mb_free_blocks(), fast commit replay can end up marking as free blocks that are already marked as such. This causes corruption of the buddy bitmap so we need to regenerate it in that case.
