From 1466a21997212a5fb33d5da9357841972b28b007 Mon Sep 17 00:00:00 2001 From: Jay Vosburgh Date: Tue, 6 Nov 2007 13:33:28 -0800 Subject: bonding: fix rtnl locking merge error Looks like I incorrectly merged one of the rtnl lock changes, so that one function, bonding_show_active_slave, held rtnl but didn't release it, and another, bonding_store_active_slave, never held rtnl but did release it. Fixed so the first function doesn't mess with rtnl, and the second correctly acquires and releases rtnl.
