Stefan Hajnoczi 729962f6db blockdev: acquire AioContext in change-backing-file ... Add dataplane support to the change-backing-file QMP commands. By acquiring the AioContext we avoid race conditions with the dataplane thread which may also be accessing the BlockDriverState. Note that this command operates on both bs and a node in its chain (image_bs). The bdrv_chain_contains(bs, image_bs) check guarantees that bs and image_bs are in the same AioContext.
