[PATCH v3 0/3] cpuacct: split usage into user_usage and sys_usage
From: Zhao Lei
Date: Thu Mar 17 2016 - 00:22:05 EST
Sometimes, cpuacct.usage is not detialed enough to user
to see how much usage a group used. We want to know how
much time it used in user mode and how much in kernel mode.
This patch introduce some more files to tell user these information.
# ls /sys/fs/cgroup/cpuacct/cpuacct.usage*
1: Remove some unnecessary locks and so some cleanup based on
suggestion from Peter Zijlstra <peterz@xxxxxxxxxxxxx>
1: Rebase on top of 4.5-rc6
2: Fix little spelling typo in description.
3: Fix line over 80 characters

cpuacct: rename parameter in cpuusage_write for readability
cpuacct: split usage into user_usage and sys_usage.
