[RFC] rcu: doc: update example about stale data

From: Joel Fernandes (Google)
Date: Sat Oct 27 2018 - 22:21:17 EST


The RCU example for 'rejecting stale data' on system-call auditting
stops iterating through the rules if a deleted one is found. It makes
more sense to continue looking at other rules once a deleted one is
rejected. Although the original example is fine, this makes it more
meaningful.
