I currently have the two here in -rcu, most likely for v5.15 (as in the merge window after the upcoming one): 2b7cb9d95ba4 ("doc: Clarify and expand RCU updaters and corresponding readers") c6ef58907d22 ("doc: Give XDP as example of non-obvious RCU reader/updater pairing") I am happy taking it, but if you really would like to add it to your series, please do take both. ;-) Thanx, Paul
