Subject: [Qemu-devel] [PATCH v3 0/2] aio: Use epoll in aio_poll()
Date: Mon, 26 Oct 2015 14:39:40 +0800	[thread overview]
Message-ID: <1445841582-17755-1-git-send-email-famz@redhat.com> (raw)

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.
