From: Zefan Li Subject: [PATCH v4 1/3] sched: fix confusing PFA_NO_NEW_PRIVS constant Date: Thu, 25 Sep 2014 09:40:17 +0800 Message-ID: <54237281.5020308@huawei.com> Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Return-path: Sender: cgroups-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-ID: Content-Type: text/plain; charset="us-ascii" To: Tejun Heo Cc: LKML , Cgroups , Peter Zijlstra , Ingo Molnar , Miao Xie , Kees Cook , Tetsuo Handa , David Rientjes Commit 1d4457f99928 ("sched: move no_new_privs into new atomic flags") defined PFA_NO_NEW_PRIVS as hexadecimal value, but it is confusing because it is used as bit number. Redefine it as decimal bit number. Note this changes the bit position of PFA_NOW_NEW_PRIVS from 1 to 0.
