[Qemu-devel] [PULL v2 03/44] block: mark AioContext as recursive |

From: Paolo Bonzini <address@hidden>
AioContext can be accessed recursively, in fact that's what we do with
aio_poll. Marking the GSource as recursive avoids that GLib blocks it
and unblocks it around every call to aio_dispatch, which is a pretty
expensive operation.
