From 5009010fbf54bdc27e57baca490e1f9d6a4609e0 Mon Sep 17 00:00:00 2001 From: Matan Barak Date: Thu, 3 Aug 2017 16:06:58 +0300 Subject: [PATCH] IB/core: Declare an object instead of declaring only type attributes Switch all uverbs_type_attrs_xxxx with DECLARE_UVERBS_OBJECT macros. This will be later used in order to embed the object specific methods in the objects as well.
