[Qemu-block] [PATCH v3 0/2] aio: Use epoll in aio_poll()

[Fam Zheng]

v3: Remove the redundant check in aio_epoll_try_enable. [Stefan]

v2: Merge aio-epoll.c into aio-posix.c. [Paolo]
    Capture some benchmark data in commit log.

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: Introduce aio_context_setup
  aio: Introduce aio-epoll.c
