Subject: [PATCH v4 14/18] scsi: target: Rename sbc_ops to exec_cmd_ops
Date: Fri, 24 Feb 2023 11:44:58 -0600	[thread overview]
Message-ID: <20230224174502.321490-15-michael.christie@oracle.com> (raw)
In-Reply-To: <20230224174502.321490-1-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.
