Subject: [PATCH 2/7] rc80211-pid: add kerneldoc for tunable parameters
Date: Sun, 23 Dec 2007 04:40:32 +0100	[thread overview]
Message-ID: <20071223044032.4ccece3e@morte> (raw)
In-Reply-To: <20071223033633.710907923@polimi.it>

Add a kerneldoc description for parameters which are tunable through debugfs.
