Subject: Re: [PATCH v5] sched_ext: Refresh scx idle state during idle-to-idle
transitions
Hi Andrea,
kernel test robot noticed the following build warnings:
[auto build test WARNING on tip/sched/core]
[also build test WARNING on linus/master v6.13-rc6 next-20250109]
[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]
