[PATCH 0/4] rcu: Unify a bit [non-]PREEMPT expedited quiescent state report

From: Frederic Weisbecker
Date: Thu Sep 16 2021 - 08:10:58 EST


This eventually removes rcu_data.exp_deferred_qs to use
rcu_data.cpu no_qs.b.exp instead.

For those like me who need a headlamp to walk there: https://ibb.co/3d06r0V
