Comment 6 Branislav Blaškovič 2012-12-10 13:40:11 UTC

Fix verified:

  # rpm -q util-linux-ng
  util-linux-ng-2.17.2-12.8.el6

  # man 8 moun
       inode_readahead_blks=n
              This  tuning  parameter  controls  the  maximum  number of inode table blocks that
              ext4’s inode table readahead algorithm will pre-read into the buffer  cache.   The
              value must be a power of 2. The default value is 32 blocks.
