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
