Kyber I/O scheduler tunables
===========================

The only two tunables for the Kyber scheduler are the target latencies for
reads and synchronous writes. Kyber will throttle requests in order to meet
these target latencies.

read_lat_nsec
-------------
Target latency for reads (in nanoseconds).

write_lat_nsec
--------------
Target latency for synchronous writes (in nanoseconds).
