For RCU-sched, a context switch\nis a quiescent state, pure and simple, just like it always has been.\nFor RCU-preempt, a context switch is in no way a quiescent state, but\nspecial handling is required when a task blocks in an RCU read-side\ncritical section.\n\nHowever, the callout from the scheduler and the outer loop in ksoftirqd\nstill calls something named rcu_sched_qs(), whose name is no longer\naccurate. Furthermore, when rcu_check_callbacks() notes an RCU-sched\nquiescent state, it ends up unnecessarily (though harmlessly, aside\nfrom the performance hit) enqueuing the current task if it happens to\nbe running in an RCU-preempt read-side critical section. This not only\nincreases the maximum latency of scheduler_tick(), it also needlessly\nincreases the overhead of the next outermost rcu_read_unlock() invocation.\n\nThis patch addresses this situation by separating the notion of RCU\u0027s\ncontext-switch handling from that of RCU-sched\u0027s quiescent states.\nThe context-switch handling is covered by rcu_note_context_switch() in\ngeneral and by rcu_preempt_note_context_switch() for preemptible RCU.\nThis permits rcu_sched_qs() to handle quiescent states and only quiescent\nstates. It also reduces the maximum latency of scheduler_tick(), though\nprobably by much less than a microsecond. Finally, it means that tasks\nwithin preemptible-RCU read-side critical sections avoid incurring the\noverhead of queuing unless there really is a context switch.\n\nSuggested-by: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\nAcked-by: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\nSigned-off-by: Paul E.

The three different roles of migration_thread() are\nsplitted into three separate cpu_stop callbacks -\nmigration_cpu_stop(), active_load_balance_cpu_stop() and\nsynchronize_sched_expedited_cpu_stop() - and each use case now simply\nasks cpu_stop to execute the callback as necessary.\n\nsynchronize_sched_expedited() was implemented with private\npreallocated resources and custom multi-cpu queueing and waiting\nlogic, both of which are provided by cpu_stop.\nsynchronize_sched_expedited_count is made atomic and all other shared\nresources along with the mutex are dropped.\n\nsynchronize_sched_expedited() also implemented a check to detect cases\nwhere not all the callback got executed on their assigned cpus and\nfall back to synchronize_sched().

However, this patch preserves\nthe paranoid check using a cpumask to record on which cpus the stopper\nran so that it can serve as a bisection point if something actually\ngoes wrong theree.\n\nBecause the internal execution state is no longer visible,\nrcu_expedited_torture_stats() is removed.\n\nThis patch also renames cpu_stop threads to from \"stopper/%d\" to\n\"migration/%d\". The names of these threads ultimately don\u0027t matter\nand there\u0027s no reason to make unnecessary userland visible changes.\n\nWith this patch applied, stop_machine() and sched now share the same\nresources. stop_machine() is faster without wasting any resources and\nsched migration users are much cleaner.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nAcked-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Dipankar Sarma \u003cdipankar@in.ibm.com\u003e\nCc: Josh Triplett \u003cjosh@freedesktop.org\u003e\nCc: Paul E.
