[Cluster-devel] [GFS2 PATCH 02/28] gfs2: Report errors before withdraw

[Bob Peterson <rpeterso@redhat.com>]

From: Andreas Gruenbacher <agruenba@redhat.com>

In gfs2_rgrp_verify and compute_bitstructs, make sure to report errors before
withdrawing the filesystem: otherwise, when we withdraw first and withdraw is
configured to panic, we'll never get to the error reporting.
