1 Known issues/TODO (for steady-state)
3 - Allow user to specify the frequency of measurements
5 - Better documentation for output
7 - Report read, write, trim IOPS/BW separately
9 - Semantics for the ring buffer ss->head are confusing. ss->head points
10 to the beginning of the buffer up through the point where the buffer
11 is filled for the first time. afterwards, when a new element is added,
12 ss->head is advanced to point to the second element in the buffer. if
13 steady state is attained upon adding a new element, ss->head is not
14 advanced so it actually does point to the head of the buffer.
