    If the swap-in problem exists.

    I can see it being triggered artificially because we still
    unmap too many pages in the pageout path, but if we fix
    shrink_cache() to not unmap the whole inactive list when
    we're under continuous memory pressure but only the end of
    the list where we're actually reclaiming pages, maybe then
    many of the minor page faults we're seeing under such
    loads will just disappear.

    Not to mention the superfluous IO being scheduled today.

    regards,
