I'm pretty sure it would either be neutral overall or a reduction (ie: sizeof merged vm_page_t <= sizeof existing vm_page_t + sizeof pv_entry) since we can drop a pointer from pv_entry. I well recall your previous objection to something else that would have increased this earlier on. ;-) Cheers, -Peter To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
