[Qemu-devel] [PATCH 0/7] AIO nested loop and bdrv_drain_all changes |

This series includes several changes that, in different ways, touch the
aio.c main loop.
Patches 1 and 2 let the tools use timers.
Patches 3 to 6 simplify the aio loop by removing the separate
process_queue callback, and by adding a return value to qemu_aio_wait.
(Mostly extracted from my threading experiments, and retested).
Patch 7 is zwu's patch to drain requests correctly in the presence of
I/O throttling. This version does not add bdrv_drain; see comments in
the patch and on the mailing list.
Paolo Bonzini (6):
qemu-io: use main_loop_wait
qemu-tool: map vm_clock to rt_clock
posix-aio: merge posix_aio_process_queue and posix_aio_read
aio: remove process_queue callback and qemu_aio_process_queue
aio: return "AIO in progress" state from qemu_aio_wait
aio: simplify qemu_aio_wait
Zhi Yong Wu (1):
block: add the support to drain throttled requests
