Or the filesystem could just call into it's own setattr method
internally. For that we'd switch back to passing the iattr to
->setsize. For a filesystem that doesn't do anything special for
ATTR_SIZE ->setsize could point to the same function as ->setattr.
For filesystem where's it's really different they could be separate or
share helpers.
