I have a number of Qemu VMs. Over the weekend I updated to the latest

disk errors. Strange thing is, my arm VM is working flawlessly.
These VM disk images are all qcow. The i386 and x86-64 ones I converted
to qcow2 and they now work fine. The arm one is still qcow and is still
working fine.
We're seeing the same on qemu-kvm.git. I tracked it down to following
commits:

qcow: add qcow_aio_setup helper
This one has an obvious bug. Does the following change help?
