Subject: [Patch v6 02/22] CIFS: SMBD: Introduce kernel config option CONFIG_CIFS_SMB_DIRECT
Date: Sat, 4 Nov 2017 22:43:44 -0700 [thread overview]
Message-ID: <20171105054404.23886-3-longli@exchange.microsoft.com> (raw)
In-Reply-To: <20171105054404.23886-1-longli@exchange.microsoft.com>
From: Long Li <longli@microsoft.com>
SMB Direct is a protocol for transferring SMB packets over RDMA. It was
introduced with Windows Serer 2012 and SMB 3.0.
With CONFIG_CIFS_SMB_DIRECT=y, SMB Direct code is built as part of CIFS.
