  "message": "stop_machine: Change cpu_stop_queue_two_works() to rely on stopper-\u003eenabled\n\nChange cpu_stop_queue_two_works() to ensure that both CPU\u0027s have\nstopper-\u003eenabled \u003d\u003d T or fail otherwise.\n\nThis way stop_two_cpus() no longer needs to check cpu_active() to\navoid the deadlock. This patch doesn\u0027t remove these checks, we will\ndo this later.\n\nNote: we need to take both stopper-\u003elock\u0027s at the same time, but this\nwill also help to remove lglock from stop_machine.c, so I hope this\nis fine.\n\nSigned-off-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nSigned-off-by: Peter Zijlstra (Intel) \u003cpeterz@infradead.org\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul E.
