- * struct cmbdata -- channel measurement block data for user space
- *
- * @size:	size of the stored data
- * @ssch_rsch_count: XXX
- * @sample_count:
- * @device_connect_time:
- * @function_pending_time:
- * @device_disconnect_time:
- * @control_unit_queuing_time:
- * @device_active_only_time:
- * @device_busy_time:
- * @initial_command_response_time:
- *
- * all values are stored as 64 bit for simplicity, especially
- * in 32 bit emulation mode. All time values are normalized to
- * nanoseconds.
- * Currently, two formats are known, which differ by the size of
- * this structure, i.e. the last two members are only set when
- * the extended channel measurement facility (first shipped in
- * z990 machines) is activated.
- * Potentially, more fields could be added, which results in a
- * new ioctl number.
