From 6756ae4b4e97aba48c042b4aa6b77a18f507d2cb Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Mon, 20 Mar 2006 22:23:58 -0800 Subject: [NET]: Convert RTNL to mutex. This patch turns the RTNL from a semaphore to a new 2.6.16 mutex and gets rid of some of the leftover legacy. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
