commit 3650d4e5b13d219ee03802c507569bb0e608023f
Author: Karsten Loesing <karsten.loesing at gmx.net>
Date: Tue Jan 12 19:28:17 2016 +0100
Ignore dirreq stats in legacy module.
We're not using directory-request statistics in the legacy module
anymore, which only produces servers.csv and bandwidth.csv. Taking
them out will make it easier to refactor the legacy module later.
