Liu Xiaodong 924d4bf32d poller: add busy wait mechanism for intr ... For pollers that don't natively support interrupts, using a busy wait mechanism temporarily. An interrupt falicity for busy wait will be registered for non-periodic poller. Internally, an eventfd is created to each busy wait poller. Write the eventfd when set interrupt mode, and only read the eventfd when set back to poll mode, then the busy wait poller will be called repeatly in interrupt mode.
