From 9bdcc88fa03a09c1f0478c0d7443d0aba7872210 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Thu, 19 Apr 2012 13:40:37 +0000 Subject: [PATCH] net decnet: Convert to use register_net_sysctl Using an ascii path to register_net_sysctl as opposed to the slightly awkward ctl_path allows for much simpler code.
