From 4813ceb154c194395dda8c6817e1f06c000470d2 Mon Sep 17 00:00:00 2001 From: Samuel Thibault Date: Wed, 9 Jan 2013 08:43:53 +0000 Subject: mini-os: Notify shutdown through weak function call instead of wake queue To allow for more flexibility, this notifies domain shutdown through a function rather than a wake queue, to let the application use a wake queue only if it wishes.
