From: Alex Ng <ale...@messages.microsoft.com>

When left uninitialized, this sometimes fails the following check in
post_status():

        if (!time_after(now, (last_post_time + HZ))) {
                return;
        }

This causes unnecessary delays in reporting memory pressure to host after
booting up.
