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* /sys/fs/cgroup/cpuacct/cpuacct.usage /sys/fs/cgroup/cpuacct/cpuacct.usage_percpu /sys/fs/cgroup/cpuacct/cpuacct.usage_user /sys/fs/cgroup/cpuacct/cpuacct.usage_percpu_user /sys/fs/cgroup/cpuacct/cpuacct.usage_sys /sys/fs/cgroup/cpuacct/cpuacct.usage_percpu_sys Changelog v2->v3: 1: Remove some unnecessary locks and so some cleanup based on suggestion from Peter Zijlstra <pet...@infradead.org> Changelog v1->v2: 1: Rebase on top of 4.5-rc6 2: Fix little spelling typo in description. 3: Fix line over 80 characters Yang Dongsheng (2): cpuacct: rename parameter in cpuusage_write for readability cpuacct: split usage into user_usage and sys_usage.
