From 87ccbb1f943625884b824c5560f635dcea8e4510 Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Tue, 4 Sep 2018 21:53:51 +0200 Subject: [PATCH] rtnetlink: move type calculation out of loop I don't see how the type - which is one of RTM_{GETADDR,GETROUTE,GETNETCONF} - can change. So do the message type calculation once before entering the for loop. Signed-off-by: Christian Brauner Signed-off-by: David S.
