Hi Wanpeng Li, I have just noticed 11c731e81bb0 (mm/mempolicy: fix !vma in new_vma_page()) and I am not sure I understand it. Your changelog claims " page_address_in_vma() may still return -EFAULT because of many other conditions in it. As a result the while loop in new_vma_page() may end with vma=NULL. "
And the patch handles hugetlb case only. I was wondering what are those "other conditions" that failed in the BUG_ON mentioned in the changelog? Could you be more specific please?
