Subject: sched: move the __update_rq_clock() call to scheduler_tick()
X-Git-Tag: v2.6.23-rc3~73^2~8
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=546fe3c909b0a4235c7237c210da483eaaac1edc;p=linux-2.6

sched: move the __update_rq_clock() call to scheduler_tick()

move the __update_rq_clock() call from update_cpu_load() to
scheduler_tick().

( identity transformation that causes no change in functionality. )

this allows the direct use of rq->clock in ->task_tick() functions.
