All three roles are\nhardcoded into migration_thread() and determining which job is\nscheduled is slightly messy.\n\nThis patch kills migration_thread and replaces all three uses with\ncpu_stop. 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(). If called with cpu hotplug blocked,\ncpu_stop already guarantees that and the condition cannot happen;\notherwise, stop_machine() would break. 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.

This problem has been avoided\nby (1) making rcutorture run only three seconds of every six by default,\n(2) adding a CONFIG_RCU_TORTURE_TEST_RUNNABLE that permits rcutorture\nto be quiesced at boot time, and (3) adding a sysctl in /proc named\n/proc/sys/kernel/rcutorture_runnable that permits rcutorture to be\nquiesced and unquiesced when built into the kernel.\n\nPlease note that this /proc file is -not- available when rcutorture\nis built as a module.

This\napproach is problematic, since it requires every kernel thread to either\nset PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn\u0027t\ncare for the freezing of tasks at all.\n\nIt seems better to only require the kernel threads that want to or need to\nbe frozen to use some freezer-related code and to remove any\nfreezer-related code from the other (nonfreezable) kernel threads, which is\ndone in this patch.\n\nThe patch causes all kernel threads to be nonfreezable by default (ie. to\nhave PF_NOFREEZE set by default) and introduces the set_freezable()\nfunction that should be called by the freezable kernel threads in order to\nunset PF_NOFREEZE. It also makes all of the currently freezable kernel\nthreads call set_freezable(), so it shouldn\u0027t cause any (intentional)\nchange of behaviour to appear.

This patch adds a \"SUCCESS\"/\"FAILURE\" string to the line\nthat flags the end of the test, where it can easily be seen with \"dmesg |\ntail\" at the end of the test. Also adds tests of architecture-specific\nmemory barriers -- or, more likely, of the RCU torture test itself.\n\nCc: \u003cvatsa@in.ibm.com\u003e\nSigned-off-by: \"Paul E.

This is needed due to the\ncontinued changes to the RCU infrastructure to accommodate dynamic ticks,\nCPU hotplug, realtime, and so on. Most of the code is in a separate file\nthat is compiled only if the CONFIG variable is set. Documentation on how\nto run the test and interpret the output is also included.\n\nThis code has been tested on i386 and ppc64, and an earlier version of the\ncode has received extensive testing on a number of architectures as part of\nthe PREEMPT_RT patchset.\n\nSigned-off-by: \"Paul E.
