There may be additional objects in the various caches. If this is a UP system then some will certainly be in the per cpu cache. You can push these back into the free lists by draining the array cache. If you allocate objects on a slab that is fresh (no objects in it) then only full slabs will be used. The remaining objects will end up on the per cpu lists where they can be consumed without more work on the full/partial arrays. - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
