    That's fine - the superblock lock doesn't need to be re-entrant, because
    __GFP_IO is quite sufficient for that one.

    The thing I want to make re-entrant is just semaphore accesses: at the
    point where we would otherwise deadlock on the writer semaphore it's much
    better to just allow nested writes. I suspect all filesystems can already
    handle nested writes - they are a lot easier to handle than truly
    concurrent ones.
