Subject: [PATCH 11/11] liblockdep: preload helper
Date: Wed,  6 Feb 2013 17:11:34 -0500	[thread overview]
Message-ID: <1360188694-25077-12-git-send-email-sasha.levin@oracle.com> (raw)
In-Reply-To: <1360188694-25077-1-git-send-email-sasha.levin@oracle.com>

This is a simple wrapper to make using liblockdep on existing applications
much easier.

After running 'make && make install', it becomes quite simple to test things
with liblockdep. For example, to try it on perf:

	liblockdep perf

No other integration required.
