From 910d6c320cac65c81d66e8fd30dca167092722eb Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Tue, 12 Feb 2008 22:16:33 -0800 Subject: [PATCH] [GENETLINK]: Relax dances with genl_lock. The genl_unregister_family() calls the genl_unregister_mc_groups(), which takes and releases the genl_lock and then locks and releases this lock itself. Relax this behavior, all the more so the genl_unregister_mc_groups() is called from genl_unregister_family() only. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
