[Cluster-devel] [PATCH 1/5] gfs2_edit: Initialize metafds fully in savemetaopen

[Andrew Price <anprice@redhat.com>]

Coverity showed that savemetaopen() can return a metafd without
initializing the gzfd member. This isn't currently a problem as we only
use gzfd when it is set but this patch initializes the metafd fully to
avoid future problems.
