It would be possible to allocate the buffer so that data portion of
write requests get the required alignment.  But that obviously means
that other type of requests won't be aligned (which shouldn't be a
problem AFAICS).

To do that, you basically have to copy the fuse_loop* function that
you need and change the buffer allocation code to your needs.

Not the nicest solution, but should work.
