Cover letter [PATCH 0/2] rcu/ftrace: Add rcu_dereference_raw_notrace() and friends
Paul,
As you suggesed using the name "*_notrace", I updated my patch. There's two patches now.
The first patch adds two new APIs to the RCU system.
rcu_dereference_raw_notrace() hlist_for_each_entry_rcu_notrace()
I needed the second one as the function tracer uses that too and it calls rcu_dereference_raw().
Is this acceptable for you? If so can you give me your acked-by, so that I can push this up to Linus. Otherwise, the system locks up when doing function tracing with too much RCU debug running.
Thanks,
-- Steve
