Yes, but the point of code-freeze (as opposed to just feature-freeze) is that
only real bugfixes go in.

The Amiga doesn't share many drivers. Parport is the only one where the
high-level drivers are exposed to so many details of the hardware. The only
place I can think of where there's an equivalent 3-layer structure is SCSI,
and things are very different there.

Allowing parport_share to own the irq isn't much different to what we have now
(aside from the switching details). I think that having the lowlevel driver
in control is definitely the right way to go in the long term.
