  These two patches clean up the process of scanning the CPU.

Patch 1 stops checking for a new idle core in time
if an idle core has already been found.

Patch 2 tries to minimize false attempts by adjusting the order
of scanning CPU.

v1->v2:
    - Simplified patch1 code and add
      "Acked-by: Mel Gorman <mgorman@techsingularity.net>"
    - Modify commit description to make it more clear

[v1] https://lore.kernel.org/all/20221021061558.34767-1-jiahao.os@bytedance.com

Hao Jia (2):
  sched/numa: Stop an exhastive search if an idle core is found
  sched/core: Adjusting the order of scanning CPU
