Subject: [PATCH 10/15] nvmet: Rename nvmet_rw_len to nvmet_rw_data_len
Date: Mon,  6 Jan 2020 15:37:31 +0200	[thread overview]
Message-ID: <20200106133736.123038-12-maxg@mellanox.com> (raw)
In-Reply-To: <20200106133736.123038-1-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.
