Re: [PATCH v4 00/11] hugetlb: Factorize hugetlb architecture primitives

Hi Mike, Thanks for your review. I'm going to fix the 2nd patch as you said, you're right, no need to move the #include at the bottom of the file. I'm going to post a v5, add -mm in cc and ask for inclusion in their tree. Thanks again for your time, Alex On 07/26/2018 09:16 PM, Mike Kravetz
