Subject: sched: Rename ttwu_post_activation() to ttwu_do_wakeup()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=23f41eeb42ce7f6f1210904e49e84718f02cb61c;p=openwrt%2Fstaging%2Fblogic.git

sched: Rename ttwu_post_activation() to ttwu_do_wakeup()

The ttwu_post_activation() code does the core wakeup, it sets TASK_RUNNING
and performs wakeup-preemption, so give is a more descriptive name.
