Hmm... I am not aware of for_each_process_rcu(), but looking at this
change I guess it includes something like scope_guard(rcu) ?

Perhaps makes sense, but the naming looks sligthly confusing to me.
I mean, to for_each_process_rcu() looks like (say) list_for_each_entry_rcu()
where _rcu has another meaning...
