[Cluster-devel] [gfs2-utils PATCH 0/7] fsck.gfs2 performance improvements

[Bob Peterson <rpeterso@redhat.com>]

My recent set of patches to fsck.gfs2 saved a lot of memory, thus
enabling us to run fsck.gfs2 on much larger file systems. However,
it slowed things down and our performance regressed. This is a set
of seven patches designed to improve performance again. There are
probably more improvements I can make, but I've been busy with kernel
work, so it's not my primary focus. If I come up with more patches,
I'll post them later.

Bob Peterson (7):
  fsck.gfs2: Don't bother to pass bl blockmap pointer
  fsck.gfs2: Remember the previous rgrp pointer for speed
  fsck.gfs2: Don't set gfs1rg pointer unless we need to
  fsck.gfs2: Make _fsck_bitmap_set not send a return code
  fsck.gfs2: convert fsck_bitmap_set to a macro
  fsck.gfs2: Speed up function bitmap_type
  fsck.gfs2: Make pass2 go by directory rbtree for performance
