I pulled this from your -dev branch for 6.16. I checked and this patch is the
only one changed so feel free to not re-send the whole series (I will be
resending it anyway once I have all the topic branches).

Also, I added your sign off as it was missing:
[PATCH 03/12] rcutorture: Split out beginning and end from
rcu_torture_one_read()

thanks,

 - Joel
