Pull workqueue fixes from Tejun Heo: - An unbound worker pool could be freed while still reachable through the pending-activation list, leading to a use-after-free. Unlink before dropping the reference - On PREEMPT_RT, the BH workqueue kick raised softirqs from preemptible context, tripping a lockdep assertion and possibly losing concurrently raised softirq bits - Draining BH work off a dead CPU nests two pools' callback locks, which lockdep misreported as recursive locking. The nesting cannot deadlock. Annotate it - Reject watchdog thresholds that overflow the conversion to jiffies - Make the drgn workqueue dump script work again on kernels and vmcores from before the workqueue attrs field rename * tag 'wq-for-7.3-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: tools/workqueue/wq_dump.py: Support backward compatibility for wq->attrs rename workqueue: reject watchdog thresholds that overflow jiffies workqueue: Fix unbound pool lifetime for pending pwqs workqueue: Use raise_softirq() to trigger softirq in irq_work handler workqueue: Annotate cb_lock nesting when draining a dead BH pool
