  "message": "rcu: Remove rcu_needs_cpu_flush() to avoid false quiescent states\n\nThe purpose of rcu_needs_cpu_flush() was to iterate on pushing the\ncurrent grace period in order to help the current CPU enter dyntick-idle\nmode.  However, this can result in failures if the CPU starts entering\ndyntick-idle mode, but then backs out.  In this case, the call to\nrcu_pending() from rcu_needs_cpu_flush() might end up announcing a\nnon-existing quiescent state.\n\nThis commit therefore removes rcu_needs_cpu_flush() in favor of letting\nthe dyntick-idle machinery at the end of the softirq handler push the\nloop along via its call to rcu_pending().\n\nSigned-off-by: Paul E. McKenney \u003cpaulmck@linux.vnet.ibm.com\u003e\n",
