  "message": "sched: Replace use of entity_key()\n\n\"entity_key()\" is only used in \"__enqueue_entity()\" and\nits only function is to subtract a tasks vruntime by\nits groups minvruntime.\nBefore this patch a rbtree enqueue-decision is done by\ncomparing two tasks in the style:\n\n\t\"if (entity_key(cfs_rq, se) \u003c entity_key(cfs_rq, entry))\"\n\nwhich would be\n\n\t\"if (se-\u003evruntime-cfs_rq-\u003emin_vruntime \u003c entry-\u003evruntime-cfs_rq-\u003emin_vruntime)\"\n\nor (if reducing cfs_rq-\u003emin_vruntime out)\n\n\t\"if (se-\u003evruntime \u003c entry-\u003evruntime)\"\n\nwhich is\n\n\t\"if (entity_before(se, entry))\"\n\nSo we do not need \"entity_key()\".\nIf \"entity_before()\" is inline we will also save one subtraction (only one,\nbecause \"entity_key(cfs_rq, se)\"  was cached in \"key\")\n\nSigned-off-by: Stephan Baerwolf \u003cstephan.baerwolf@tu-ilmenau.de\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLink: http://lkml.kernel.org/n/tip-ns12mnd2h5w8rb9agd8hnsfk@git.kernel.org\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
