    If the system is running a heavy load of processes then concurrent reclaim
    can isolate a large numbe of pages from the LRU. /proc/meminfo and the
    output generated for an OOM do not show how many pages were isolated.

    This patch shows the information about isolated pages.

    Page migration can also isolate a large number of pages from the LRU. But
    the new counters are not used there.
