Subject: [PATCH 3/5] cpuacct: Initialize cpuacct subsystem earlier
Date: Thu, 28 Mar 2013 15:21:14 +0800 [thread overview]
Message-ID: <5153EF6A.9050906@huawei.com> (raw)
In-Reply-To: <5153EF24.3040608-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>
Initialize cpuacct before the scheduler is functioning, so when
cpuacct_charge() and cpuacct_account_field() are called, task_ca()
won't return NULL.
