Commit-ID: 84fb5a182d39221b89f205365386df243135d622 Gitweb: http://git.kernel.org/tip/84fb5a182d39221b89f205365386df243135d622 Author: Leo Yan <leo.yan@linaro.org> AuthorDate: Tue, 15 Sep 2015 18:57:37 +0800 Committer: Ingo Molnar <mingo@kernel.org> CommitDate: Fri, 18 Sep 2015 09:23:15 +0200 sched/fair: Polish comments for LOAD_AVG_MAX Macro LOAD_AVG_MAX is defined far away from the precompuated tables for decay calculation in code; So explicitly comments for this. Also fix one typo: s/LOAD_MAX_AVG/LOAD_AVG_MAX.
