Subject: [B.A.T.M.A.N.] [PATCH] remove unnecessary logspam
Date: Wed, 4 Jun 2014 21:53:36 +0200 [thread overview]
Message-ID: <1401911616-18318-1-git-send-email-gaul@web-yard.de> (raw)
This patch removes unnecessary logspam which resulted from superfluous
calls to net_ratelimit(). With the supplied patch, net_ratelimit() is
called after the loglevel has been checked.
