Does anyone know what M_KERNEL is sys/malloc.h is supposed to do? It
is used in precisely two places in the code as far as I can tell:
vm/default_pager.c: if (swap_pager_swp_alloc(object, M_KERNEL) != 0) {
vm/default_pager.c: if (swap_pager_swp_alloc(object, M_KERNEL) != 0) {
vm/swap_pager.c: spc->spc_bp = malloc(sizeof(*bp), M_TEMP, M_KERNEL);
But kern/kern_malloc.c doesn't appear to really use it. On the otherhand
I do see lots of absolute comparison of the malloc 'flags' to M_WAITOK
(0) or M_NOWAIT which the use of M_KERNEL would interfere with. I can't
tell if the side effects are something that are expected, or if the
side effects are a bug.
Anybody know?
