Subject: [PATCH tip/core/rcu 0/12] RCU flavor consolidation cleanups for v5.1
Date: Wed, 9 Jan 2019 13:18:30 -0800	[thread overview]
Message-ID: <20190109211830.GA30595@linux.ibm.com> (raw)

Hello!

This series contains additional cleanups for RCU flavor consolidation:

1-2.	Replace scheduler _sched() APIs with _rcu() counterparts.

3.	Renaming and commenting changes due to only one rcuo kthread
	per CPU.

4.	Make expedited IPI handler return after handling critical section.
	This is a maintainability and performance change.

5.	Inline force_quiescent_state() into rcu_force_quiescent_state().

6.	Eliminate RCU_BH_FLAVOR and RCU_SCHED_FLAVOR.

7.	Inline rcu_kthread_do_work() into its sole remaining caller.

8.	Determine expedited-GP IPI handler at build time.

9.	Consolidate PREEMPT and !PREEMPT synchronize_rcu_expedited().

10.	Consolidate PREEMPT and !PREEMPT synchronize_rcu().

11.	Inline _synchronize_rcu_expedited() into synchronize_rcu_expedited().

12.	Discard separate per-CPU callback counts.

							Thanx, Paul
