Subject: [PATCH 11/16] nvmet: rename nvmet_rw_len to nvmet_rw_data_len
Date: Tue, 19 May 2020 17:05:58 +0300	[thread overview]
Message-ID: <20200519140603.166576-12-maxg@mellanox.com> (raw)
In-Reply-To: <20200519140603.166576-1-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.
