Yes, I should've added a link to that in my cover letter,
in the next revision I'll point to:
https://lore.kernel.org/xen-devel/20210115083000.14186-1-jgross@suse.com/

I've reordered the patches and changed the base, it should be gone the
next I do git format-patch:
https://github.com/edwintorok/xen/pull/1/commits
Will also remove
https://github.com/edwintorok/xen/pull/1/commits/47dd1d9b99b9210e94fbd4af28afee8088d5267
once I implemented the change in oxenstored to not return BUSY that we
discussed.
