For what it's worth, the v2 protocol was only used very very early on,
and the only difference between the v2 and the v3 protocol is that the
v3 protocol supported the expiration ioctl.

There is no reason to believe there are any current users of the v2
protocol, but from the kernel point of view it is a strict subset of the
v3 protocol, so adding support for it is effectively no-op.
