Subject: [PATCH 1/5] vtime: Gather vtime declarations to their own header file
Date: Thu, 25 Oct 2012 19:47:59 +0200 [thread overview]
Message-ID: <1351187283-20715-2-git-send-email-fweisbec@gmail.com> (raw)
In-Reply-To: <1351187283-20715-1-git-send-email-fweisbec@gmail.com>
These APIs are scattered around and are going to expand a bit.
Let's create a dedicated header file for sanity.
