From 0f1db069b6c5e7f7ddcdcc9c64fd4b6dbe4afcdf Mon Sep 17 00:00:00 2001 From: Steve Sistare Date: Wed, 3 Jan 2024 12:05:32 -0800 Subject: [PATCH] cpus: check running not RUN_STATE_RUNNING When a vm transitions from running to suspended, runstate notifiers are not called, so the notifiers still think the vm is running. Hence, when we call vm_start to restore the suspended state, we call vm_state_notify with running=1. However, some notifiers check for RUN_STATE_RUNNING. They must check the running boolean instead. No functional change.
