This one seemed straightforward and I heard no objections to the previous
two-patch series, so I queued them for the v5.13 merge window, thank you!
If any of them need adjustment, please send me the updated patch and
tell me which one it replaces. Something about -rcu being in heavy
experimental mode at the moment. ;-)
Thanx, Paul

Thank you!
I would have given the go-ahead for the other series next week Monday,
but I think that's a holiday anyway. :-)
Thanks,

It is indeed! I guess you had Wednesday last week, with next up being
