From e7918e96193dbaf334c480ddde58ebc1370a84f6 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Thu, 1 Jun 2023 13:51:37 +0200 Subject: bochs: mark more functions as coroutine_fns and GRAPH_RDLOCK 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.
