Subject: [PATCH v16 2/4] RDMA/core: Add device method for registering dma-buf based memory region
Date: Tue, 15 Dec 2020 13:27:14 -0800 [thread overview]
Message-ID: <1608067636-98073-3-git-send-email-jianxin.xiong@intel.com> (raw)
In-Reply-To: <1608067636-98073-1-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.
