>From 71da2480d4bac0fc598e4d1f05f71aba8b980bc4 Mon Sep 17 00:00:00 2001 From: Peter Xu Date: Thu, 17 Nov 2022 16:29:15 -0500 Subject: [PATCH] selftests/vm: use memfd for hugepage-mmap test Content-type: text/plain This test was overlooked with a hard-coded mntpoint path in test when we're removing the hugetlb mntpoint in commit 0796c7b8be84. Fix it up so the test can keep running.
