From: Rik van Riel Date: Mon, 27 Jan 2014 22:03:47 +0000 (-0500) Subject: sched/numa: Rename variables in task_numa_fault() X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=58b46da336a9312b2e21bb576d1c2c484dbf6257;p=openwrt%2Fstaging%2Fblogic.git sched/numa: Rename variables in task_numa_fault() We track both the node of the memory after a NUMA fault, and the node of the CPU on which the fault happened. Rename the local variables in task_numa_fault to make things more explicit.
