FYI: A while ago I looked into folding the work here into xfsaild.
While soing the periodic ail push there aka just waking up with a
timeout which we did more often anyway at that point was easy, getting
the log force / dummy log never really worked out.

I think at least the former probably should be dropped here as well.
