--- Comment #2 from Chris Wilson <chris at chris-wilson.co.uk> ---
For reference,

commit d224985a5e312ab05b624143a3fd9bb91b53e52a
Author: Peter Zijlstra <peterz at infradead.org>
Date:   Thu Mar 15 11:41:39 2018 +0100

    sched/wait, drivers/drm: Convert wait_on_atomic_t() usage to the new
wait_var_event() API

    The old wait_on_atomic_t() is going to get removed, use the more
    flexible wait_var_event() API instead.

    Unlike wake_up_atomic_t(), wake_up_var() will issue the wakeup
    even if the variable is not 0.

    No change in functionality.

did impact upon mock_breadcrumbs. Whether that alone is the cause...
