Kernel module which implements asynchronous server

Hi there. I want to find out is there built-in mechanism, which I can use in kernel module programming similar to poll/epoll/select? I found function sock_poll, but it is not exported with EXPORT_SYMBOL macro. Tried to use poll from socket's ops, but file field in socket structure is NULL (which needs for poll function as 1st argument) after sock_create/sock_create_lite. Maybe there is an example of this kind of project, but I didn't find it. Thank you in advance.
