Michael Brown 99ef98d0bf ATA devices are now asynchronous. The ATA layer itself now performs the
async_wait(), though we may wish to move this higher up the stack, and
consider making the block device model asynchronous.  (There is only a
marginal cost for synchronous devices, since they can simply call
async_done() before returning; async_wait() will work seamlessly in this
situation).
