Subject: [PATCH tip/core/rcu 0/13] Miscellaneous fixes for 4.6
Date: Tue, 23 Feb 2016 21:12:21 -0800	[thread overview]
Message-ID: <20160224051221.GA17099@linux.vnet.ibm.com> (raw)

Hello!

This series contains miscellaneous fixes for 4.6:

1.	rcu: Assign false instead of 0 for ->core_needs_qs

2.	Update rcu_report_qs_rsp() comment for RCU's grace-period kthreads.

3.	Stop treating in-kernel CPU-bound workloads as errors, and stop
	IPIing such CPUs unless it is necessary.  (If the loop contains
	cond_resched_rcu_qs(), then it is not necessary!)

4.	Set rdp->gpwrap when CPU is idle instead of doing it backwards.

5.	Correct no-expedite console messages.

6.	Remove useless rcu_data_p when !PREEMPT_RCU, courtesy of Chen Gang.

7-9.	Allow fields to be marked private to allow sparse to complain
	about unauthorized access for rcu_node:: lock and
	irq_common_data::state_use_accessors, courtesy of Boqun Feng.

10.	Make rcu/tiny_plugin.h explicitly non-modular, courtesy of
	Paul Gortmaker.

11.	Document unique-name limitation for DEFINE_STATIC_SRCU(),
	which results from the same per-CPU variable limitation.

12.	Catch up rcu_report_qs_rdp() comment with reality.

13.	Remove rcu_user_hooks_switch, courtesy of Yang Shi.

							Thanx, Paul
