Subject: [PATCH v5 4/5] p7300: add performance tests for clean

From: Erik Elfström <[email-masked]>
Date: Sun, 26 Apr 2015 08:49:44 +0200

The tests are run in dry-run mode to avoid having to restore the test
directories for each timed iteration. Using dry-run is an acceptable
compromise since we are mostly interested in the initial computation
of what to clean and not so much in the cleaning it self.
