Subject: [PATCH v6 2/4] RDMA/core: Add device method for registering dma-buf base memory region
Date: Fri, 23 Oct 2020 09:39:59 -0700 [thread overview]
Message-ID: <1603471201-32588-3-git-send-email-jianxin.xiong@intel.com> (raw)
In-Reply-To: <1603471201-32588-1-git-send-email-jianxin.xiong@intel.com>
Dma-buf based memory region requires one extra parameter and is processed
quite differently. Adding a separate method allows clean separation from
regular memory regions.
