From 1ce97e564b628bee30b8dbb64e5e653a484308f6 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Thu, 21 May 2009 15:18:19 +0100 Subject: 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.
