fsck.gfs2: fsck.gfs2: Ask to reclaim unlinked meta per-rgrp only
From: Bob Peterson <email@example.com>
Before this patch, fsck.gfs2 would ask for every unlinked metadata bit
whether you wanted to reclaim it as free space. This patch makes it
ask only once per resource group, and reports which resource group
so that the user doesn't think it's stuck in an infinite loop.
