Subject: [PATCH 0/4] ex4 block bitmap prefetching
Date: Fri, 17 Jul 2020 11:53:48 -0400
Message-ID: <20200717155352.1053040-1-tytso@mit.edu> (raw)

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
