No, I'll pick it up for 4.9 merge.  Mikulas added it for sparc or
something.  I cannot recall _the_ reason (I wasn't maintaining DM back
then) but at the time both Alasdair and Joe Thornber reasoned that it
needed to go -- and that if it was really needed that it should be done
in terms of a proper patch to sched.h, etc.

So I'm not sure how this dm-bufio local cond_resched() wrapper still got
in... happy to take your patch.

Please respond with whatever SOB you'd like applied to the patch header.

Thanks,
Mike
