-/**
- * struct cmbdata - channel measurement block data for user space
- * @size: size of the stored data
- * @elapsed_time: time since last sampling
- * @ssch_rsch_count: number of ssch and rsch
- * @sample_count: number of samples
- * @device_connect_time: time of device connect
- * @function_pending_time: time of function pending
- * @device_disconnect_time: time of device disconnect
- * @control_unit_queuing_time: time of control unit queuing
- * @device_active_only_time: time of device active only
- * @device_busy_time: time of device busy (ext. format)
- * @initial_command_response_time: initial command response time (ext. format)
- *
- * 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 would result in a
- * new ioctl number.
