Also __wake_up_locked() is now exported\nas to pair it with the above macros.\n\nThe use case of this new facility is when one uses wait queue\u0027s lock\nto protect a data structure. This may be advantageous if the\nstructure needs to be protected by a spinlock anyway. In particular,\nwith additional spinlock the following code has to be used to wait\nfor a condition:\n\nspin_lock(\u0026data.lock);\n...\nfor (ret \u003d 0; !ret \u0026\u0026 !(condition); )

wait_event_interruptible() locks the wait\nqueue\u0027s lock anyway so there is a unlock+lock sequence where it could\nbe avoided.\n\nTo avoid those problems and benefit from wait queue\u0027s lock, a code\nsimilar to the following should be used:\n\n/* Waiting */\nspin_lock(\u0026data.wqh.lock);\n...\nret \u003d wait_event_interruptible_locked(data.wqh,

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.

This is\nprimarily to replace and unify RT workqueue usage in stop_machine and\nscheduler migration_thread which currently is serving multiple\npurposes.\n\nFour functions are provided - stop_one_cpu(), stop_one_cpu_nowait(),\nstop_cpus() and try_stop_cpus().\n\nThis is to allow clean sharing of resources among stop_cpu and all the\nmigration thread users. One stopper thread per cpu is created which\nis currently named \"stopper/CPU\". This will eventually replace the\nmigration thread and take on its name.\n\n* This facility was originally named cpuhog and lived in separate\n files but Peter Zijlstra nacked the name and thus got renamed to\n cpu_stop and moved into stop_machine.c.\n\n* Better reporting of preemption leak as per Peter\u0027s suggestion.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nAcked-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Dimitri Sivanich \u003csivanich@sgi.com\u003e\n" }, { "commit": "ee84b8243b07c33a5c8aed42b4b2da60cb16d1d2", "tree": "a5b3cad55179fe8340c6422deaf6e11120222ad1", "parents": [ "ad4ba375373937817404fd92239ef4cadbded23b" ], "author": { "name": "Paul E.
