From 38b8dd6f87398524d02c21ff614c507ba8c9d295 Mon Sep 17 00:00:00 2001 From: Michael Wang Date: Tue, 3 Jul 2012 14:34:02 +0800 Subject: [PATCH] sched: Remove useless code in yield_to() It's impossible to enter the else branch if we have set skip_clock_update in task_yield_fair(), as yield_to_task_fair() will directly return true after invoke task_yield_fair().
