Subject: [PATCH rdma-next v2 12/20] IB/core: Introduce DECLARE_UVERBS_GLOBAL_METHODS

From: Yishai Hadas <yishaih@...lanox.com>

Introduce a new macro to be used for global methods on a singleton
object.

This macros sets internally the type_attrs to be NULL as such an object
can't be created.

Downstream patches from this series will use this macro.
