[PATCH 10/12] qcow2: mark more functions as coroutine_fns and GRAPH_RDLOCK |
|
Date: |
Thu, 1 Jun 2023 13:51:43 +0200 |
Mark functions as coroutine_fn when they are only called by other coroutine_fns
and they can suspend. Change calls to co_wrappers to use the non-wrapped
functions, which in turn requires adding GRAPH_RDLOCK annotations.
