Hi,
There is no need no explicitly start a RCU read section if one has already
been started implicitly by spin_lock().

Simplify the code and remove the inner rcu_read_lock() invocation.
I'm not going argue if this is a good or not but: If you intend to get
this merged I suggest you rebase your series (or what is left since I
think a few patches got merged) on top of current tree and resend them
individually targeting the relevant tree/ list. Otherwise everyone might
think someone else is in charge of this big series.
