GFS2: Take glock reference in examine_bucket() We need to check the glock ref counter in a race free way in order to ensure that the gfs2_glock_hold() call will succeed. The easiest way to do that is to simply take the reference count early in the common code of examine_bucket, skipping any glocks with zero ref count. That means that the examiner functions all need to put their reference on the glock once they've performed their function.
