    The xfs warning during truncate will be fixed with a later update
    (Nathan is currently working on it).

    next thing to do is to fixup the merging in mprotect.

    In the meantime this is already mergeable in -mm if Andrew is

    I'm not touching mremap at this time (i'll reistantiate the merging in
    mprotect first, then Hugh testcase will work as well as in mainline). I
    wait comments on the truncate/mremap race fixes (they clearly partly
    collides with prio-tree but part of them seems shareable). That race
    isn't trivial to fix but at the same time it doesn't worry me much right
    now. I could add the semaphore, but mremap is an extreme fast path for
    some workload like apache, so I'm not going to risk a
    scalability-slowdown in there with an obviously safe patch of taking the
    i_shared_sem semaphore, because even if that race triggers the kernel
    shouldn't crash anymore.
