v3
- Add Patch 2 to fix a race condition in test-bdrv-drain. This was the CI
failure that bumped this patch series from Kevin's pull request.
- Add missing 051.pc.out file. I tried qemu-system-aarch64 to see of 051.out
also needs to be updated, but no changes were necessary. [Kevin]
v2
- Add patch to remove AIOCBInfo->get_aio_context() [Kevin]
- Add patch to use qemu_get_current_aio_context() in block-coroutine-wrapper so
that the wrappers use the current AioContext instead of
bdrv_get_aio_context().
Switch blk_aio_*() APIs over to multi-queue by using
qemu_get_current_aio_context() instead of blk_get_aio_context(). This change
will allow devices to process I/O in multiple IOThreads in the future.
The final patch requires my QIOChannel AioContext series to pass
tests/qemu-iotests/check -qcow2 281 because the nbd block driver is now
accessed from the main loop thread in addition to the IOThread:
