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.

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