I don't really like moving this stuff to libfrog. The whole point of
libxfs/libxfs_priv.h is to define the kernel wrapper stuff that
libxfs needs to compile and should never be seen by anything outside
libxfs/...

Indeed, we -cannot- use spinlocks in userspace code, so I really
don't see why we'd want to make them more widely visible to the
userspace xfsprogs code...

Cheers,

Dave.
