mm: memcontrol: replace node summing with memcg_page_state()
mainline inclusion from mainline-5.2-rc1 commit 22796c84 category: bugfix bugzilla: 51815, https://gitee.com/openeuler/kernel/issues/I3IJ9I CVE: NA ------------------------------------------------- Instead of adding up the node counters, use memcg_page_state() to get the memcg state directly. This is a bit cheaper and more stream-lined. Link: http://lkml.kernel.org/r/20190228163020.24100-4-hannes@cmpxchg.org Signed-off-by:Johannes Weiner <hannes@cmpxchg.org> Reviewed-by:
