From mboxrd@z Thu Jan 1 00:00:00 1970 From: Matan Barak Subject: [PATCH RFC 04/10] IB/core: Declare a type instead of declaring only type attributes Date: Wed, 19 Apr 2017 18:20:19 +0300 Message-ID: <1492615225-55118-5-git-send-email-matanb@mellanox.com> References: <1492615225-55118-1-git-send-email-matanb@mellanox.com> Return-path: In-Reply-To: <1492615225-55118-1-git-send-email-matanb-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org> Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org Cc: Doug Ledford , Jason Gunthorpe , Sean Hefty , Liran Liss , Majd Dibbiny , Yishai Hadas , Ira Weiny , Christoph Lameter , Leon Romanovsky , Tal Alon , Matan Barak List-Id: linux-rdma@vger.kernel.org Switch all uverbs_type_attrs_xxxx with DECLARE_UVERBS_TYPE macros. This will be later used in order to embed the types specific actions in the types as well.
