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