From f1a438d813d416fa9f4be4e6dbd10b54c5938d89 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Thu, 9 Aug 2007 11:16:45 +0200 Subject: [PATCH] sched: reorder update_cpu_load(rq) with the ->task_tick() call Peter Williams suggested to flip the order of update_cpu_load(rq) with the ->task_tick() call. This is a NOP for the current scheduler (the two functions are independent of each other), ->task_tick() might create some state for update_cpu_load() in the future (or in PlugSched).
