H A D | aio.h | diff 845ca10dd089b4e48f0a79bad005fb30eb77584e Wed Jul 09 04:53:01 CDT 2014 Paolo Bonzini <pbonzini@redhat.com> AioContext: take bottom halves into account when computing aio_poll timeout
Right now, QEMU invokes aio_bh_poll before the "poll" phase of aio_poll. It is simpler to do it afterwards and skip the "poll" phase altogether when the OS-dependent parts of AioContext are invoked from GSource. This way, AioContext behaves more similarly when used as a GSource vs. when used as stand-alone.
As a start, take bottom halves into account when computing the poll timeout. If a bottom half is ready, do a non-blocking poll. As a side effect, this makes idle bottom halves work with aio_poll; an improvement, but not really an important one since they are deprecated.
