from race and so on. More details can be found in git log.
Thanks!

ext4: avoid to use preallocated blocks if EXT4_MB_HINT_GOAL_ONLY is
set
ext4: get correct ext4_group_info in ext4_mb_prefetch_fini
ext4: correct calculation of s_mb_preallocated
ext4: correct start of used group pa for debug in ext4_mb_use_group_pa
