y stopped and freed if (likely(worker)) { // true => read before CPU2 acted cq->notify = RVT_CQ_NONE; cq->triggered++; kthread_queue_work(worker, &cq->comptask); BANG: worker has been flushed/stopped/freed in the meantime. This patch solves this by protecting the critical sections by rdi->n_cqs_lock. It seems that this lock is not much contended and looks reasonable for this purpose. One catch is that rvt_cq_enter() might be called from IRQ context. Therefore we must always take the lock with IRQs disabled to avoid a possible deadlock.
