From dac9c9790e542777079999900594fd069ba10489 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Sun, 7 Oct 2018 20:16:24 -0700 Subject: net: Add extack to nlmsg_parse Make sure extack is passed to nlmsg_parse where easy to do so. Most of these are dump handlers and leveraging the extack in the netlink_callback. Signed-off-by: David Ahern Acked-by: Christian Brauner Signed-off-by: David S.
