Subject: [PATCH 11/16] nvmet: Rename nvmet_rw_len to nvmet_rw_data_len
Date: Mon,  2 Dec 2019 16:48:07 +0200	[thread overview]
Message-ID: <20191202144812.147686-13-maxg@mellanox.com> (raw)
In-Reply-To: <20191202144812.147686-1-maxg@mellanox.com>

From: Israel Rukshin <israelr@mellanox.com>

The function doesn't add the metadata length (only data length is
calculated). This is preparation for adding metadata (T10-PI) support.
