Second round of gfs2_rename lock re-ordering to allow Anaconda adding root partition on top of gfs2. Previous to this patch the recursive lock detector in glock.c can be triggered due to attempting to lock the rgrp twice. This fixes it by checking to see whether the rgrp is already locked. This fixes Red Hat bugzilla #221237 Signed-off-by: S. Wendy Cheng <wcheng@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
