However, the code in __rwsem_do_wake() breaks this\nrule, it updates -\u003eactivity after _all_ readers waken up, this may give\nsome reader a wrong -\u003eactivity value, thus cause rwsem_is_locked() behaves\nwrong.\n\nQuote from Andrew:\n\n\"\n- we have one or more processes sleeping in down_read(), waiting for access.\n\n- we wake one or more processes up without altering -\u003eactivity\n\n- they start to run and they do rwsem_is_locked(). This incorrectly\n returns \"false\", because the waker process is still crunching away in\n __rwsem_do_wake().\n\n- the waker now alters -\u003eactivity, but it was too late.\n\"\n\nSo we need get a spinlock to protect this.
