Heesub Shin 1dd61aa31c mm/zbud: init user ops only when it is needed ... When zbud is initialized through the zpool wrapper, pool->ops which points to user-defined operations is always set regardless of whether it is specified from the upper layer. This causes zbud_reclaim_page() to iterate its loop for evicting pool pages out without any gain. This patch sets the user-defined ops only when it is needed, so that zbud_reclaim_page() can bail out the reclamation loop earlier if there is no user-defined operations specified.
