Hi Jason, It seems that kbuild has put my patch on to the wrong git tree for test. I have checked on for-next tree according to the reproduce steps, it didn't report such warnings. Could I just ignore this kbuild report? On 2018/2/26 20:46, kbuild test robot wrote: > Hi Yixian, > > Thank you for the patch!
