Subject: [uml-devel] [PATCH 3/11] UML - Simplify interval setting
Date: Wed, 19 Sep 2007 13:02:23 -0400 [thread overview]
Message-ID: <20070919170223.GA10171@c2.user-mode-linux.org> (raw)
set_interval took a timer type as an argument, but it always specified
a virtual timer. So, it is not needed, and it is gone, and
set_interval is simplified appropriately.
