The variables best_prio and best_prio_seen (inherited from the old\nmove_tasks()) were only required to handle problems caused by the\nactive/expired arrays, the order in which they were processed and the\npossibility that the task with the highest priority could be on either.\n These issues are no longer present and the extra overhead associated\nwith their use is unnecessary (and possibly wrong).\n\n2. In the absence of CONFIG_FAIR_GROUP_SCHED being set, the same\nthis_best_prio variable needs to be used by all scheduling classes or\nthere is a risk of moving too much load. E.g. if the highest priority\ntask on this at the beginning is a fairly low priority task and the rt\nclass migrates a task (during its turn) then that moved task becomes the\nnew highest priority task on this_rq but when the sched_fair class\ninitializes its copy of this_best_prio it will get the priority of the\noriginal highest priority task as, due to the run queue locks being\nheld, the reschedule triggered by pull_task() will not have taken place.\n This could result in inappropriate overriding of skip_for_load and\nexcessive load being moved.\n\nThe attached patch addresses these problems by deleting all reference to\nbest_prio and best_prio_seen and making this_best_prio a reference\nparameter to the various functions involved.\n\nload_balance_fair() has also been modified so that this_best_prio is\nonly reset (in the loop) if CONFIG_FAIR_GROUP_SCHED is set.

However, the new modular\ndesign of the new CFS scheduler allows a simpler solution to be adopted\nand this patch addresses that solution by:\n\n1. adding a new function, move_one_task(), to be used by\nactive_load_balance(); and\n2. making move_tasks() a single purpose function that tries to move a\nspecified weighted load and returns 1 for success and 0 for failure.\n\nOne of the consequences of these changes is that neither move_one_task()\nor the new move_tasks() care how many tasks sched_class.load_balance()\nmoves and this enables its interface to be simplified by returning the\namount of load moved as its result and removing the load_moved pointer\nfrom the argument list. This helps simplify the new move_tasks() and\nslightly reduces the amount of work done in each of\nsched_class.load_balance()\u0027s implementations.\n\nFurther simplification, e.g. changes to balance_tasks(), are possible\nbut (slightly) complicated by the special needs of load_balance_fair()\nso I\u0027ve left them to a later patch (if this one gets accepted).\n\nNB Since move_tasks() gets called with two run queue locks held even\nsmall reductions in overhead are worthwhile.\n\n[ mingo@elte.hu ]\n\nthis change also reduces code size nicely:\n\n text data bss dec hex filename\n 39216 3618 24 42858 a76a sched.o.before\n 39173 3618 24 42815 a73f sched.o.after\n\nSigned-off-by: Peter Williams \u003cpwil3058@bigpond.net.au\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "f1a438d813d416fa9f4be4e6dbd10b54c5938d89", "tree": "0aeb01cea731ed44d765c6a2d599edbd6db5c9c2", "parents": [ "0915c4e89d311948b67cdd4c183a2efbcafcc9f9" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Aug 09 11:16:45 2007 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Aug 09 11:16:45 2007 +0200" }, "message": "sched: reorder update_cpu_load(rq) with the -\u003etask_tick() call\n\nPeter Williams suggested to flip the order of update_cpu_load(rq) with\nthe -\u003etask_tick() call.
