(I know it doesn't throw the whole thing out, I watched it work.) :)
Is it safe to assume that while this code is running, the program will not
be run and try to be swapped back in? I thought about that but wasn't sure
if the kernel could get into a swap-fight with one part (swap_out_pid)
throwing the program out and the page faults bringing it back in. Doesn't
sound likely but I suppose the worst that can happen is I lock my machine
up. :)
I'll clean up it and see what I can do. Any idea what GFP_ it should use
or is 0 adequate?
