Hi Ingo,
kernel test robot noticed the following build warnings:
[auto build test WARNING on tip/sched/core] [also build test WARNING on linux/master linus/master peterz-queue/sched/core v6.9-rc2 next-20240405] [If your patch is applied to the wrong git tree, kindly drop us a note. And when submitting patch, we suggest to use '--base' as documented in https://git-scm.com/docs/git-format-patch#_base_tree_information]
