"allows to $verb" is not idiomatic English; the options are "allows
$subject to $verb" or "allows ${verb}ing"

Not really a net win in lines of code; but I'll have to see how the
other patches in the series are made easier by this. It relies on the
fact that the NBD protocol states that negotiation phase is synchronous
(at one point, it was argued that negotiation, like transmission, could
allow out-of-order replies from the server, but we got that fixed in the
spec to match existing practice, and this patch cements the fact that we
are processing exactly one option at a time).
Mechanically, the conversion looks sane, so:

We'll see how I feel at the end of the series.
