Subject: [PULL 05/26] cpus: check running not RUN_STATE_RUNNING
Date: Thu,  4 Jan 2024 12:31:50 +0800	[thread overview]
Message-ID: <20240104043213.431566-6-peterx@redhat.com> (raw)
In-Reply-To: <20240104043213.431566-1-peterx@redhat.com>

From: Steve Sistare <steven.sistare@oracle.com>

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.
