Subject: [PATCH] nvmet: rename nvmet_rw_len to nvmet_rw_data_len
Git-commit: 26af180c1bd9cdd6f9b96d8df58b51d5900a2978
Patch-mainline: v5.8-rc1
References: jsc#SLE-15608
The function doesn't add the metadata length (only data length is
calculated). This is preparation for adding metadata (T10-PI) support.
