Subject: [PATCH RESEND 2/2] ptrace: annotate lock context change on exit_ptrace()
Date: Sun, 26 Sep 2010 12:53:51 +0900 [thread overview]
Message-ID: <1285473231-6229-2-git-send-email-namhyung@gmail.com> (raw)
In-Reply-To: <1285473231-6229-1-git-send-email-namhyung@gmail.com>
exit_ptrace() releases and regrabs tasklist_lock but was missing
proper annotation. Add it.
