This adds hash_for_each_possible_rcu_notrace() which is basically
a notrace clone of hash_for_each_possible_rcu() which cannot be
used in real mode due to its tracing/debugging capability.

Anyone, ping. Is it good, bad, ugly (ack/nack)? Thanks!
Is there any "trivial patches" list? Could not find it on vger.

:) Was that the question?
Anyway, you cc'd all the right people already.
If no one responds after a couple weeks, either
