That results in several\nproblems:\n\n  1) the rbtree dequeue happens without waiter::task::pi_lock being held\n\n  2) the waiter task's pi_blocked_on state is not cleared, which leaves a\n     dangling pointer primed for UAF around.\n\n  3) rt_mutex_adjust_prio_chain() operates on the wrong top priority waiter\n     task\n\nUse waiter::task instead of current in all related operations in\nremove_waiter() to cure those problems.\n\n[ tglx: Fixup rt_mutex_adjust_prio_chain(), add a comment and amend the\n  \tchangelog ]"
