Subject: [PATCH 8/12] powerpc: assign PDE->data before gluing PDE into /proc tree
Date: Tue, 29 Apr 2008 15:13:18 +0400	[thread overview]
Message-ID: <1209467602-20001-8-git-send-email-den@openvz.org> (raw)
In-Reply-To: <1209467538.29647.11.camel@iris.sw.ru>

Simply replace proc_create and further data assigned with proc_create_data.
No need to check for data!=NULL after that.
