| |
the highest_flag_domain is to search the highest sched_domain containing flag, but if the lower sched_domain didn't contain the flag, but the higher sched_domain contains the flag, the function will return NULL instead of the higher sched_domain.
For example: In MC domain : no SD_ASYM_CPUCAPACITY flag; In DIE domain : containing SD_ASYM_CPUCAPACITY flag; the "highest_flag_domain(cpu, SD_ASYM_CPUCAPACITY)" will return NULL.
