From: Stefan Hajnoczi <stefa...@redhat.com> BlockDriver->bdrv_create() has been called from coroutine context since commit 5b7e1542cfa41a281af9629d31cef03704d976e6 ("block: make bdrv_create adopt coroutine").
Make this explicit by renaming to .bdrv_co_create() and add the coroutine_fn annotation. This makes it obvious to block driver authors that they may yield, use CoMutex, or other coroutine_fn APIs.
