Subject[PATCH 3/9] rcu/sync: Remove custom check for reader-section (v2)
Date
The rcu/sync code was doing its own check whether we are in a reader
section. With RCU consolidating flavors and the generic helper added in
this series, this is no longer need. We can just use the generic helper
and it results in a nice cleanup.
