Subject: [PATCH 02/11] sched: load_balance_monitor rename
Date: Sun, 06 Jan 2008 17:11:30 +0100	[thread overview]
Message-ID: <20080106162122.832609000@chello.nl> (raw)

don't start the load_balance_monitor when there is only a single cpu.
rename the kthread because its currently longer than TASK_COMM_LEN
