From 39977a83d4d8cd5e8b22ca9111a4b05851c4c418 Mon Sep 17 00:00:00 2001 From: Tom Herbert Date: Tue, 15 Dec 2015 15:41:37 -0800 Subject: BACKPORT: netlink: add a start callback for starting a netlink dump commit fc9e50f5a5a4e1fa9ba2756f745a13e693cf6a06 upstream. The start callback allows the caller to set up a context for the dump callbacks. Presumably, the context can then be destroyed in the done callback. Signed-off-by: Tom Herbert Signed-off-by: David S.
