71  * Accumulated time and queue length statistics.
72  *
73  * Accumulated time statistics are kept as a running sum of "active" time.
74  * Queue length statistics are kept as a running sum of the product of queue
75  * length and elapsed time at that length -- i.e., a Riemann sum for queue
76  * length integrated against time.  (You can also think of the active time as a
77  * Riemann sum, for the boolean function (queue_length > 0) integrated against
78  * time, or you can think of it as the Lebesgue measure of the set on which
79  * queue_length > 0.)

92  *		Time->	t1	t2	t3	t4
93  *
94  * At each change of state (entry or exit from the queue), we add the elapsed
95  * time (since the previous state change) to the active time if the queue length
96  * was non-zero during that interval; and we add the product of the elapsed time
97  * times the queue length to the running length*time sum.
98  *
99  * This method is generalizable to measuring residency in any defined system:
100  * instead of queue lengths, think of "outstanding RPC calls to server X".
101  *
102  * A large number of I/O subsystems have at least two basic "lists" of
103  * transactions they manage: one for transactions that have been accepted for
104  * processing but for which processing has yet to begin, and one for
105  * transactions which are actively being processed (but not done). For this
106  * reason, two cumulative time statistics are defined here: wait (pre-service)
107  * time, and run (service) time.
108  *
109  * All times are 64-bit nanoseconds (hrtime_t), as returned by gethrtime().
110  *
111  * The units of cumulative busy time are accumulated nanoseconds. The units of
112  * cumulative length*time products are elapsed time times queue length.
113  *
114  * Updates to the fields below are performed implicitly by calls to
115  * these functions:

124  * These fields should never be updated by any other means.
