FLUSHES_MS	The total number of milliseconds spent by all flush requests.
IO_MS	The total number of milliseconds spent doing I/Os.
IO_MS_WEIGHTED	Incremented at each I/O start, I/O completion, I/O merge, or read of these stats by the number of I/Os in progress IO_QUEUE_LENGTH times the number of milliseconds spent doing I/O since the last update of this field.
IO_QUEUE_LENGTH	Incremented as requests are given to appropriate struct request_queue and decremented as they finish.
MAJOR	The device major number.
MINOR	The device minor number.
NAME	The device name.
