:thing to do in FreeBSD ? :-)
:
:And everybody with VM clue I've asked says it would be trivial to
:flip two page-table entries, so for all I care it can be
:
: mexchangemapping(void *from, void *to, size_t length)
:
:--
:Poul-Henning Kamp | UNIX since Zilog Zeus 3.20
:phk@FreeBSD.ORG | TCP/IP since RFC 956
:FreeBSD committer | BSD since 4.3-tahoe
Or
mcopymap(from, to, length, flags)
flags:
MAP_SHARED share the same content (we back them with the
same VM objects).
MAP_PRIVATE copy on write, as if you fork()d and the parent
was the original area and the child is the new
area.
But I'm not volunteering.
