    It's not about crashing. It's about being a totally unmaintainable mess,
    with ad-hoc temporary allocations, and loops over an unknown number of

    That's _broken_. B. R. O. K. E. N.

    And in all cases there are fixes that I've pointed out. If you can't see
    that, then that's _your_ problem. If you (or others) want your code
    merged, then it had better _fix_ the total disaster before merging. It's
    that simple.

    The "lock root" thing you complain should also be easily fixable, by
    keeping the root lock a separate issue from walking the actual anon_vma
    (ie walk the anon_vma, but lock the root). You still don't have to lock
    the whole list.
