From: Johannes Weiner <hannes@cmpxchg.org> mainline inclusion from mainline-v4.20-rc1 commit e9b257ed150c1f43912bd66031185598451f68a9 category: bugfix bugzilla: 34611 CVE: NA ------------------------------------------------- The refault stats go better with the page fault stats, and are of higher interest than the stats on LRU operations. In fact they used to be grouped together; when the LRU operation stats were added later on, they were wedged in between. Move them back together. Documentation/admin-guide/cgroup-v2.rst already lists them in the right order.
