Hmm. So with this, check_object_size() seems sane, but it's only
marked "inline".

And we've had the issue that without the __always_inline, gcc will
randomly not inline things. In fact, this very pull added that to the
copy_xyz_user() functions exactly because of this issue.

Now, it may be that check_object_size() is so simple that it really
always *will* be inlined regardless, but it looks a bit dodgy.
