Subject: [PATCH 0/2 v3] ext4: use mb_optimize_scan regardless of inode format

Hello,

this patch series enables use of mballoc optimizations regardless of the inode
format. See patch 2 for details.

Changes since v2:
* Added barrier into ext4_get_allocation_groups_count() as suggested by Pedro
  Falcato
* Collected reviewed-by tags

Changes since v1:
* Added patch to make sure mballoc doesn't select group with block numbers
  greater than 2^32 for indirect block based inodes
