Subject: tracehook_notify_death: use task_detached() helper
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=bb24c679a51b1a9b726b901330649e3861814ac0;p=openwrt%2Fstaging%2Fblogic.git

tracehook_notify_death: use task_detached() helper

Now that task_detached() is exported, change tracehook_notify_death() to
use this helper, nobody else checks ->exit_signal == -1 by hand.
