    aio: implement IOCB_CMD_POLL · 2c14fa83
    Christoph Hellwig authored
    Simple one-shot poll through the io_submit() interface.  To poll for
    a file descriptor the application should submit an iocb of type
    IOCB_CMD_POLL.  It will poll the fd for the events specified in the
    the first 32 bits of the aio_buf field of the iocb.
    
    Unlike poll or epoll without EPOLLONESHOT this interface always works
    in one shot mode, that is once the iocb is completed, it will have to be
    resubmitted.
