Revision fad02c2de0623fc6d4ff12ca72b60ea521118681 authored by Johannes Weiner on 29 May 2012, 22:07:07 UTC, committed by Linus Torvalds on 29 May 2012, 23:22:28 UTC
The counter of currently swapped out pages in a memcg (hierarchy) is sitting amidst ever-increasing event counters. Move this item to the other counters that reflect current state rather than history. This technically breaks the kernel ABI, but hopefully nobody relies on the order of items in memory.stat.
