Very good, thank you!

All fair points.

I have srcunmisafe.2022.11.29a merged into -rcu immediately following
my RCU merge commit for the upcoming merge window.  My current rcu/next
branch includes it.

So if there are no mandatory-SRCU explosions in -next by Sunday December
4th, I will send Linus this commit in the merge window that is currently
slated to open the week of December 12th:

ec69c6900127 ("srcunmisafe.2022.11.29a: Make SRCU mandatory.")

As the title suggests, this includes the desired commit.

If there are explosions, well, we will deal with them and see where
we go from there.  My fallback commit would be this guy:

87492c06e68d ("Merge branches 'doc.2022.10.20a', 'fixes.2022.10.21a', 'lazy.2022.11.30a', 'srcunmisafe.2022.11.09a', 'torture.2022.10.18c' and 'torturescript.2022.10.20a' into HEAD")

This excludes that commit.  But hopefully there will be no explosions
that cannot be taken care of quickly.

Does that work for you?
