[Qemu-devel] [PATCH v2 00/15] qcow/qcow2 cleanups

[Frediano Ziglio <freddy77@gmail.com>]

These patches mostly cleanup some AIO code using coroutines.
Mostly they use stack instead of allocated AIO structure.
Feel free to collapse it too short.

  qcow: allocate QCowAIOCB structure using stack
  qcow: QCowAIOCB field cleanup
  qcow: move some blocks of code to avoid useless variable
