As I said in an earlier e-mail:

1. the common API is in throttle.h.

2. Once you configure the throttling settings you essentially only need
   to call throttle_schedule_timer() to see if a request needs to be
   throttled, and afterwards throttle_account() to register the I/O that
   has been peformed.
