[Qemu-block] [PATCH v2 0/2] Fix aio_notify_accept()

[Fam Zheng]

v2: Implement the fix following Paolo's idea.
    Testing is still in progress.

Calling aio_notify_accept(iothread->ctx) from main loop when it does
aio_poll(iothread->ctx, false) is a bug because it may steal the event needed
by aio_poll(iothread->ctx, true) in the IOThread. This can cause IOThread
hanging.

Fam Zheng (2):
  aio-posix: Don't count ctx->notifier as progress when polling
  aio: Do aio_notify_accept only during blocking aio_poll
