Date: Tue, 03 Sep 2013 13:03:41 +0800 From: Chen Gang <gang.chen@...anux.com> To: Andrew Morton <akpm@...ux-foundation.org>, bsingharora@...il.com CC: "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org> Subject: [PATCH] kernel/delayacct.c: remove redundancy checking in __delayacct_add_tsk() The wrapper function delayacct_add_tsk() already checked 'tsk->delays', and __delayacct_add_tsk() has no another direct callers, so can remove the redundancy checking code. And the label 'done' is also useless, so remove it, too.
