Isn't this a leftover thing from when dasd selected deadline
internally? I don't think we need this anymore, just kill the
select completely.

Basically yes.
We still have the recommendation to use deadline and there are some udev
rules in place which select it.
So I thought it might be a good idea to keep the line. But I am also
fine to drop it completely if you prefer this.

Stefan

I don't feel super strongly about it, but at the same time I don't
think there's a reason for it. Besides, I think everyone has deadline
enabled. So I guess we should just kill it.

OK, thanks for your opinion. I will remove the line and come up with a
different patch.
