    Unfortunately, not.

    For information, reverting just the first part of the offending commit
    (sl->timer.cb_mode) fixed the problem, while reverting only the second
    part (if (!hrtimer_active(&t->timer))) had no effect.

    Also, I found a trivially reproductible testcase : sleep 0.

    It hangs in nanosleep({0, 0}).
