Subject: [PATCH tip/core/rcu 0/5] Miscellaneous fixes for 4.9
Date: Mon, 22 Aug 2016 08:29:56 -0700 [thread overview]
Message-ID: <20160822152956.GA8160@linux.vnet.ibm.com> (raw)
Hello!
This series contains miscellaneous fixes:
1. Fix a soft lockup in the RCU's callback-offload (rcuo) kthreads,
courtesy of Ding Tianhong.
2. Use rcu_gp_kthread_wake() to wake up grace period kthreads,
avoiding spurious/redundant wakeups, courtesy of Jisheng Zhang.
3. Make wake_up_nohz_cpu() handle CPUs going offline.
4. Don't use modular infrastructure in non-modular code, courtesy
of Paul Gortmaker.
5. Avoid redundant quiescent-state chasing by more carefully
initializing flags for newly onlined CPUs.
Thanx, Paul
