Robert Watson 38c9c1708b Perform a lockless read to test whether an entropy havesting fifo is ... full, avoiding the cost of mutex operations if it is. We re-test once the mutex is acquired to make sure it's still true before doing the -modify-write part of the read-modify-write. Note that due to the maximum fifo depth being pretty deep, this is unlikely to improve harvesting performance yet. Approved by: markm		2004-08-11 03:33:32 +00:00
