Patches aim to: - add missing coroutine_fn annotation to the functions - simplify to avoid the typical "if in coroutine: fn() // else create_coroutine(fn)" already present in generated_co_wraper functions. - make sure that if a BlockDriver callback is defined as coroutine_fn, then it is always running in a coroutine. This serie is based on Kevin Wolf's series "block: Simplify drain".
