Peter Xu 12eb3c2c1a mm/swap: fix pte_same_as_swp() not removing uffd-wp bit when compare ... commit 099dd6878b9b12d6bbfa6bf29ce0c8ddd38f6901 upstream. I found it by pure code review, that pte_same_as_swp() of unuse_vma() didn't take uffd-wp bit into account when comparing ptes. pte_same_as_swp() returning false negative could cause failure to swapoff swap ptes that was wr-protected by userfaultfd.
