[Qemu-devel] [PATCH for 2.1 0/4] AioContext cleanups and optimizations |

These patches do some cleanup and optimization in AioContext land.
The first two drop AIO functions that operate on the main AioContext.
These are not needed anymore now that each BlockDriverState explicitly
operates on its own AioContext. They are independent, and can be
skipped if the maintainers prefer doing so or have comments.
Patch 3 is a testsuite change for the aio_notify optimization, and
patch 4 is the aio_notify patch, now with a better comment
about the smp_mb optimization.
Paolo Bonzini (4):
block: prefer aio_poll to qemu_aio_wait
block: drop aio functions that operate on the main AioContext
test-aio: fix GSource-based timer test
AioContext: speed up aio_notify
