[Qemu-devel] [PATCH v2 0/6] block: avoid recursive AioContext acquire in bdrv_inactivate_all()

[Stefan Hajnoczi]

v2:
 * Added docs/devel/multiple-iothreads.txt doc update [Kevin]
 * Added qemu-iotests 203 test case [Kevin]
 * Added iothread_stop() race fix to make 203 reliable

Patch 1 is Paolo's recursive locking removal in bdrv_inactivate_all().  This
solve migration hangs and is the main point of the patch series.

Patches 2-6 add a qemu-iotests test case and update the multiple-iothreads.txt
documentation to discourage recursive AioContext locking.
