By using the generic list_lru code, we can now separate the per sb quota list locking from the lru locking. The lru lock is made into the inner-most lock. As a result of this new lock order, we may occasionally see items on the per-sb quota list which are "dead" so that the two places where we traverse that list are updated to take account of that. As a result of this patch, the gfs2 quota shrinker is now NUMA zone aware, and we are also laying the foundations for further improvments in due course.
