Right now we use a kernel\nthread and set_cpus_allowed but in doing so we wake up the previous cpu\nunnecessarily.\n\nSome ftrace output shows this:\n\nprevious cpu (2):\n[002]  7.022331: sched_switch: task swapper:0 [140] \u003d\u003d\u003e rtasd:194 [120]\n[002]  7.022338: sched_switch: task rtasd:194 [120] \u003d\u003d\u003e migration/2:9 [0]\n[002]  7.022344: sched_switch: task migration/2:9 [0] \u003d\u003d\u003e swapper:0 [140]\n\nnext cpu (3):\n[003]  7.022345: sched_switch: task swapper:0 [140] \u003d\u003d\u003e rtasd:194 [120]\n[003]  7.022371: sched_switch: task rtasd:194 [120] \u003d\u003d\u003e swapper:0 [140]\n\nWe can use schedule_delayed_work_on and avoid the unnecessary wakeup.\n\nSigned-off-by: Anton Blanchard \u003canton@samba.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n",
