No need for poll_table_entry, we just need a wait_queue_head.
poll_table_entry is an select.c internal (except for two nasty driver) -
neither epoll nor most in-kernel callers use it.

Well, you need the poll_table for the "poll_wait()", and you would
need to be able to have multiple wait-queues even though you only have
one file you're waiting for.

But yes, it doesn't really need to be the full complex poll_table_entry model.
