From 36dffab679c7eeb91c2507400cf4da6e9e01164e Mon Sep 17 00:00:00 2001 From: Vaidyanathan Srinivasan Date: Sat, 20 Dec 2008 10:06:38 +0530 Subject: [PATCH] sched: nominate preferred wakeup cpu, fix Andrew Morton reported: > kernel/sched.c: In function 'schedule': > kernel/sched.c:3679: warning: 'active_balance' may be used uninitialized in this function > > This warning is correct - the code is buggy. In sched.c load_balance_newidle, there's real potential use of uninitialised variable - fix it.
