Subject: [PATCH 10/15] nvmet: rename nvmet_rw_len to nvmet_rw_data_len
Date: Tue, 28 Apr 2020 16:11:30 +0300
Message-ID: <20200428131135.211521-11-maxg@mellanox.com> (raw)
In-Reply-To: <20200428131135.211521-1-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.
