Subject: [PATCH 08/12] iucv: convert cpu notifier to return encapsulate errno value
Date: Thu, 18 Mar 2010 18:05:20 +0900	[thread overview]
Message-ID: <1268903124-10237-8-git-send-email-akinobu.mita@gmail.com> (raw)
In-Reply-To: <1268903124-10237-1-git-send-email-akinobu.mita@gmail.com>

By the previous modification, the cpu notifier can return encapsulate
errno value. This converts the cpu notifiers for iucv.
