Subject: [PATCH v2 11/11] liblockdep: preload helper

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:

	lockdep perf

No other integration required.
