From b6544c0b4cf2bd96195f3cdb7cebfb35090fc557 Mon Sep 17 00:00:00 2001 From: Jamal Hadi Salim Date: Sat, 18 Jun 2005 22:54:12 -0700 Subject: [NETLINK]: Correctly set NLM_F_MULTI without checking the pid This patch rectifies some rtnetlink message builders that derive the flags from the pid. It is now explicit like the other cases which get it right. Also fixes half a dozen dumpers which did not set NLM_F_MULTI at all.
