The timeouts are for:
a) A fallback for backing stores which don't wake up waiters in blk_congestion_wait() (eg: NFS).

It can probably be removed with some work, and additional locking. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
