I think this commit required for 10-STABLE too:
op@opn hardenedBSD.git> git grep "vm pagequeue"
sys/vm/vm_page.c: mtx_init(&pq->pq_mutex, pq->pq_name,
"vm pagequeue",
op@opn hardenedBSD.git> git grep "vm page queue"
sys/kern/subr_witness.c: { "vm page queue", &lock_class_mtx_sleep },
sys/kern/subr_witness.c: { "vm page queue", &lock_class_mtx_sleep },
op@opn hardenedBSD.git>
It would be nice to MFC them to 10-STABLE too.
