i've followed this thread for some time now and something i dont completely
grasp.... isnt the whole idea of optimising the copying of (big) stuff
inside and in/out the kernel to userland not one of the design principles
of the UVM memory system ?
Shouldn't we rather look at ways to shift/replace memory pages between
userland and kernel? or otherwise change the API to make it possible? I
think thats more the way to go than trying to keep on copying stuff... that
was the way of the old memory system.
OK... maybe i am a bit too optimistic, but maybe its also a clue :-D
