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
Friday April 2?  ;-)
