[Qemu-block] [PATCH 0/3] aio: Use epoll in aio_poll()

[Fam Zheng]

This series adds the ability to use epoll in aio_poll() on Linux. It's switched
on in a dynamic way rather than static for two reasons: 1) when the number of
fds is not high enough, using epoll has little advantage; 2) when an epoll
incompatible fd needs to be handled, we need to fall back.  The epoll is
enabled when a fd number threshold is met.

  aio: Move AioHandler struct to header
  aio: Introduce aio_context_setup
