Subject: [PATCH 01/11] scsi: target: Rename sbc_ops to exec_cmd_ops
Date: Fri, 3 Jun 2022 01:55:26 -0500 [thread overview]
Message-ID: <20220603065536.5641-2-michael.christie@oracle.com> (raw)
In-Reply-To: <20220603065536.5641-1-michael.christie@oracle.com>
The next patches allow us to call the block layer's pr_ops from the
backends. This will require allowing the backends to hook into the cmd
processing for SPC commands, so this renames sbc_ops to a more generic
exec_cmd_ops.
Signed-off-by: Mike Christie <michael.christie@oracle.com>
