Subject: Re: [PATCH 00/14] Fix bug about invalid wake up problem
Date: Fri, 30 Aug 2013 07:39:34 +0800 [thread overview]
Message-ID: <521FDBB6.1030601@huawei.com> (raw)
In-Reply-To: <1377784669-28140-1-git-send-email-huawei.libin@huawei.com>
Hi all,
I'm so sorry, please ignore this patch set!
I have realized that there is no this problem in our kernel.
Preempt_schedule() has set PREEMPT_ACTIVE before calling
__schedule() and __schedule will check it if current state is not
TASK_RUNNING, avoiding this preemption.
