I think it will be best if I push it to Linus asap to fix the build break
on arm64 and mips, introduced by my pull request. It is really strange that
I got no report from linux-next about that issue, although this patch was
there for about 2 weeks.

Right, I'm working on providing an update which will address the issues
pointed by Grant, but I got sick and had to take some days off. I still
didn't recover completely, but I hope I will manage to finish them by
the end of the week.

Best regards
