Since gfs2_permission may be called either from the VFS (in which case we need to obtain a shared glock) or from GFS2 (in which case we already have a glock) we need to test to see whether or not a lock is required. The original test was buggy due to a potential race. This one should be safe. This fixes Red Hat bugzilla #217129 Signed-off-by:Steven Whitehouse <swhiteho@redhat.com>
