[PATCH v2 17/20] scsi: target: Rename sbc_ops to exec_cmd_ops

Mike Christie
2022-08-09T00:06:12Z

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.
