If you fix the issue, kindly add following tag as appropriate
Reported-by: kernel test robot <lkp@xxxxxxxxx>
The variable name is newpte. But it's written as new_pte latter. Many thanks for report!
BTW: Since this is not a formal patch (no compile tested). Is Reported-by tag still needed?
Hi Miaohe,
Please ignore the tag, it's only a suggestion, the bot doesn't
know the entire picture.
Best Regards,
Rong Chen
Thanks!
