GFS2: Be more aggressive in reclaiming unlinked inodes
This patch increases the frequency with which gfs2 looks for unlinked, but still allocated inodes. Its the equivalent operation to ext3's orphan list, but done with bitmaps in the resource groups. This also fixes a bug where a field in the rgrp was too small. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
