From cd490c5b285544dc1319cf79c2ca0528a6447f61 Mon Sep 17 00:00:00 2001 From: Suresh Siddha Date: Tue, 6 Dec 2011 11:26:34 -0800 Subject: [PATCH] sched, nohz: Set the NOHZ_BALANCE_KICK flag for idle load balancer Intention is to set the NOHZ_BALANCE_KICK flag for the 'ilb_cpu'. Not for the 'cpu' which is the local cpu. Fix the typo.
