[Cluster-devel] GFS2: Move gfs2_recoverd into recovery.c

[Steven Whitehouse <swhiteho@redhat.com>]

Subject: [PATCH] GFS2: Move gfs2_recoverd into recovery.c

By moving gfs2_recoverd, we can make an additional function static
and it also leaves only (the already scheduled for removal) gfs2_glockd
in daemon.c.

At the same time the declaration of gfs2_quotad is moved to quota.h
to reflect the new location of gfs2_quotad in a previous patch. Also
the recovery.h and quota.h headers are cleaned up.
