This has worse conflicts, it looks like. And not particularly trivial.
Do you have a merge resolution?

We might want to consider doing a special branch for this...

Hmm... it was a clean merge on top of Linus' tree, but got conflicts with
linux-next. I guess the conflict is from other changes in the block tree?

Yeah, I can port each patch on top of the special branch. To make sure they
all work. 

Thanks,

Most likely core block changes, I would suspect, from Christoph.

I've done a for-5.20/drivers-late branch that you can base on, that
should be the sanest way to do this.
