--- Comment #1 from Ed Maste <emaste@freebsd.org> ---
Testing now.

I believe this will in practice be rare - let me know if you agree:

> crypto_dispatch()
> returns EINVAL if its argument or the callback function was NULL, and 0
> otherwise.

So aside from bugs elsewhere, crypto_dispatch should only ever return 0, and
we'd need a race with another thread that sets bp->bio_error in order to cause
an issue.
