Date: Sun, 27 May 2007 13:04:47 +0200 From: "Rafael J. Wysocki" <rjw@...k.pl> To: Andrew Morton <akpm@...ux-foundation.org> Cc: Gautham R Shenoy <ego@...ibm.com>, LKML <linux-kernel@...r.kernel.org>, Oleg Nesterov <oleg@...sign.ru>, Pavel Machek <pavel@....cz> Subject: [PATCH -mm 3/3] Freezer: Remove redundant check in try_to_freeze_tasks From: Rafael J. Wysocki <rjw@...k.pl> We don't need to check if todo is positive before calling time_after() in try_to_freeze_tasks(), because if todo is zero at this point, the loop will be broken anyway due to the while () condition being false.
