The quilt patch titled Subject: mm/hugetlb: fix hugetlbfs_pagecache_present() has been removed from the -mm tree. Its filename was hugetlb-revert-use-of-page_cache_next_miss-fix.patch This patch was dropped because it was folded into hugetlb-revert-use-of-page_cache_next_miss.patch ------------------------------------------------------ From: Dan Carpenter <dan.carpenter@xxxxxxxxxx> Subject: mm/hugetlb: fix hugetlbfs_pagecache_present() Date: Fri, 23 Jun 2023 09:26:02 +0300 The filemap_get_folio() function doesn't returns NULL, it returns error pointers. So the "return folio != NULL;" statement means hugetlbfs_pagecache_present() always returns true.
