Frederic will be doing RCU PR for v6.7 merge window

[Paul E. McKenney]

Hello, Linus,

This time, Frederic Weisbecker will be handling the RCU commits for the
upcoming v6.7 merge window.  This is once again a practice exercise,
and I will likely be returning for the v6.8 merge window.

This again covers only RCU, so I will be sending pull requests as needed
for the other topics.

Again, please let me know of any concerns or issues with this.

                                                        Thanx, Paul
