Subject: [PATCH 4/5] NFS: Convert trace points to trace markers
Date: Fri, 16 Jan 2009 11:32:14 -0500	[thread overview]
Message-ID: <4970B68E.4090602@RedHat.com> (raw)
In-Reply-To: <4970B451.4080201@RedHat.com>

This the magic that converts the trace points into trace marks
so systemtap scripts can read the data. There is a good chance
these interfaces could change, but it should not effect the 
trace points define in the code.
