And just for reference, here is my patchset I've created sometime ago
which streamlines the sdev and starget lifetime. I think I've tried
to send it upstream at one point but never got far with it.
Be aware that it's relative to a rather git tree (2.6.22?) so
it might not apply properly. But it's mainly to get you an idea
of what I've done so far.

And would have continued pushing it if real life hadn't interfered ...

HTH.

Cheers,

Hannes
