Subject: [PATCH 0/4] ex4 block bitmap prefetching

I've revised Alex's original block allocation prefetch changes a bit,
and an option to prefetch all of the block allocation bitmaps when the
file system is mounted.  Please take a look...

Alex Zhuravlev (2):
  ext4: add prefetching for block allocation bitmaps
  ext4: skip non-loaded groups at cr=0/1 when scanning for good groups

Theodore Ts'o (2):
  ext4: indicate via a block bitmap read is prefetched via a tracepoint
  ext4: add prefetch_block_bitmaps mount options
