No. When the caches are heavily used they will need to be freed anyway since we need the space for new data to be read in. Besides, we swap_out() doesn't free any memory any more, so we need to run shrink_mmap() regardless. what we really need is somebody to try it out on 4M and 8M machines... cheers, Rik -- the flu hits, the flu hits, the flu hits -- MORE +-------------------------------------------------------------------+ | Linux memory management tour guide.
