Subject: [PATCH v5 07/11] account guest time per-cgroup as well.
Date: Wed, 9 Jan 2013 15:45:34 +0400 [thread overview]
Message-ID: <1357731938-8417-8-git-send-email-glommer@parallels.com> (raw)
In-Reply-To: <1357731938-8417-1-git-send-email-glommer@parallels.com>
We already track multiple tick statistics per-cgroup, using
the task_group_account_field facility. This patch accounts
guest_time in that manner as well.
