    Subject[PATCHv12 11/37] mm: temporally mark THP broken
    Date
    Up to this point we tried to keep patchset bisectable, but next patches
    are going to change how core of THP refcounting work.

    It would be beneficial to split the change into several patches and make
    it more reviewable. Unfortunately, I don't see how we can achieve that
    while keeping THP working.

    Let's hide THP under CONFIG_BROKEN for now and bring it back when new
    refcounting get established.
