Same alignment for the variables as for the arguments.

Move this check to th caller?  Although this and similar check in
the other file system patches miss block device nodes, for which we'd
need a special case, or one in the caller to override the attrs.

Or maybe using the file attr for this isn't actually a good idea,
and we should do an ioctl instead which automatically gets routed to
the block device fops?

.. and initialize the variable at declaration time?
