Subject: [PATCH rdma-next 6/8] RDMA: Pass uverbs_attr_bundle as part of '.reg_user_mr_dmabuf' API
From: Yishai Hadas <yishaih@...dia.com>
Pass uverbs_attr_bundle as part of '.reg_user_mr_dmabuf' API instead of
udata.
This enables passing some new ioctl attributes to the drivers, as will
be introduced in the next patches for mlx5 driver.
Change the involved drivers accordingly.
