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
