From d6ee15adec5a2345e88c680cd15ed48796c89c14 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Wed, 27 Apr 2022 15:08:29 +0200 Subject: coroutine-lock: introduce qemu_co_queue_enter_all Because qemu_co_queue_restart_all does not release the lock, it should be used only in coroutine context. Introduce a new function that, like qemu_co_enter_next, does release the lock, and use it whenever qemu_co_queue_restart_all was used outside coroutine context.
