From c75b9b10e7f09bbf9660dd20a675e0a8069bd529 Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Tue, 24 May 2011 14:18:31 +0200 Subject: [PATCH] drbd: Don't use empty nested netlink attributes Before mainline commit ea5693cc (v2.6.29-rc1), empty nested netlink attributes were not allowed. Fix that by leaving out nested attributes if they are empty and by allowing the top-level attributes to be missing.
