The readahead request is issued per segment while searching the latest super root block. This will shorten mount time after unclean unmount. A measurement shows the recovery time was reduced by more than 60 percent: e.g. real 0m11.586s -> 0m3.918s (x 2.96) Signed-off-by: Ryusuke Konishi --- Reading git-diff-tree failed
