From: Johannes Weiner Date: Tue, 29 May 2012 22:06:26 +0000 (-0700) Subject: Documentation: memcg: future proof hierarchical statistics documentation X-Git-Tag: v3.5-rc1~49^2~156 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=eb6332a54542bcd3aedb121ecb247f172b8f3602;p=profile%2Fivi%2Fkernel-x86-ivi.git Documentation: memcg: future proof hierarchical statistics documentation The hierarchical versions of per-memcg counters in memory.stat are all calculated the same way and are all named total_. Documenting the pattern is easier for maintenance than listing each counter twice.
