Subject: [PATCH 0/2] Fix poll bug

Hi,

This fixes a bug in poll wakeups, where it would wake up
unnecessarily. This is most obvious with sockets, where the socket will
wake both readers and writers when new read data is available, even if the
socket is still not writable.

Patch 1 is a simple bug I noticed while debugging the poll problem
Patch 2 is the poll fix

Dylan Yudaken (2):
  io_uring: fix ordering of args in io_uring_queue_async_work
  io_uring: only wake when the correct events are set
