Subject: Re: [PATCH-RT sched v3 1/2] RT SCHED: Optimize the enqueue and
 dequeue operations for rt_se

Hi Xavier,

kernel test robot noticed the following build warnings:

[auto build test WARNING on tip/sched/core]
[also build test WARNING on shuah-kselftest/next shuah-kselftest/fixes peterz-queue/sched/core linus/master v6.10]
[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
