static u64 throttle_seed(throttle_t *t, u32 thread_index, f64 time_now)
A throttle Used in the data plane to decide if a given hash should be throttled, i.e.
f64 * last_seed_change_time

struct throttle_t_ throttle_t
A throttle Used in the data plane to decide if a given hash should be throttled, i.e.
static int throttle_check(throttle_t *t, u32 thread_index, u64 hash, u64 seed)
