hulk inclusion category: feature bugzilla: 38261, https://bugzilla.openeuler.org/show_bug.cgi?id=23 CVE: NA --------------------------- Introduce CONFIG_SCHED_STEAL to limit the impact of steal task. 1). If turn off CONFIG_SCHED_STEAL, then all the changes will not exist, for we use some empty functions, so this depends on compiler optimization. 2). enable CONFIG_SCHED_STEAL, but disable STEAL and schedstats, it will introduce some impact whith schedstat check. but this has little effect on performance. This will be our default choice.
