Subject: [PATCH tip/core/rcu 11/12] rcu/nocb: Remove stale comment above rcu_segcblist_offload()

From: Frederic Weisbecker <frederic@...nel.org>

This commit removes a stale comment claiming that the cblist must be
empty before changing the offloading state.  This claim was correct back
when the offloaded state was defined exclusively at boot.
