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

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

Thanks,

Frederic Weisbecker (4):
      rcu: Ignore rdp.cpu_no_qs.b.exp on premptible RCU's rcu_qs()
      rcu: Remove useless WRITE_ONCE() on rcu_data.exp_deferred_qs
      rcu: Move rcu_data.cpu_no_qs.b.exp reset to rcu_export_exp_rdp()
      rcu: Remove rcu_data.exp_deferred_qs and convert to rcu_data.cpu no_qs.b.exp
