    a) It's obviously correct
    b) it's a friggin error-handling path and I'll take correctness over
    anything here.

    Keep in mind that you want to zero the area out, so at the very least
    truncate_inode_pages() + ->truncate() are needed. And locking/ordering
    consideration here are tricky enough to make duplicating them a Bad
    Thing(tm).
