Lines Matching full:lower

49  * Each cache entry holds a reference to the lower vnode
51  * entry is added the lower vnode is VREF'd.  When the
52  * alias is removed the lower vnode is vrele'd.
89  * Return a VREF'ed alias for lower vnode if already exists, else 0.
90  * Lower vnode should be locked on entry and will be left locked on exit.
105 	 * the lower vnode.  If found, the increment the null_node  in null_hashget_locked()
106 	 * reference count (but NOT the lower vnode's VREF counter).  in null_hashget_locked()
112 			 * Since we have the lower node locked the nullfs  in null_hashget_locked()
114 			 * it had been recycled before we grabed the lower  in null_hashget_locked()
182  * Vp is the alias vnode, lowervp is the lower vnode.
239 	 * We might miss the case where lower vnode sets VIRF_PGREAD  in null_nodeget()
