Subject: [PATCH 05/13] RT: Initialize the priority value
Date: Tue, 23 Oct 2007 12:50:49 -0400	[thread overview]
Message-ID: <20071023165049.5536.4280.stgit@novell1.haskins.net> (raw)
In-Reply-To: <20071023164156.5536.95573.stgit@novell1.haskins.net>

We should init the base value of the current RQ priority to "IDLE"
