I can't apply this straight off. Most of the libxfs code that is
changed is shared with the kernel code, and so the definitions of
the variables need to be the same as the kernel code. There are
reasons for the kernel code using __[u]int*_t type variants (e.g.  I
think the endian conversion static checker requires the __ variants
for host order variables), and so before making sweeping changes
like this we need to ensure that we can make the equivalent changes
to the kernel code as well...

Cheers,

Dave.
