[RFC PATCH 1/4] linsched: remove process_all_softirqs() in main loopfor accuracy
From: Michael Wang
Date: Sun Sep 02 2012 - 23:58:05 EST
From: Michael Wang <wangyun@xxxxxxxxxxxxxxxxxx>
process_all_softirqs() will handle softirq for all the cpu even
it's not the right timing for them, this will cause inaccuracy.
This patch stop invoke process_all_softirqs(), so softirq will
only be handled after timer interrupt arrived.
