I tend to agree it's buggy. I would expect the long to generate a 32
bit int even in the 64 bit kernel space unless you specifically ask
for a 64 bit long .ie. suns 'long long'. This would keep things
downward/backward compatible.

I was going to provide a patch to do something like this, but unless I
misunderstood Alan I think he said there are ioctl's which can be used
to convert the 64 bit structs while passing to 32 bit user space. I'm
getting lost finding them though...

Anyway, I guess this is only a problem while were're still limited to
32 bit user space with 64 bit kernels.
