May pool_cache_get() ever return NULL?

["J. Hannken-Illjes" <hannken%eis.cs.tu-bs.de@localhost>]

A short question:  Given a pool initialized with

        pool = pool_cache_init(SIZE, 0, 0, 0, "desc",
            NULL, IPL_NONE, NULL, NULL, NULL);

will

        pool_cache_get(pool, PR_WAITOK)

ever return NULL?
