I've also confirmed outside of the test that they are both\nindeed able to execute binaries on read-only DAX mounts.\n\nThanks to Randy Dodgen for the bug report and reproduction steps.\n\nSigned-off-by: Ross Zwisler <ross.zwisler@linux.intel.com>\nCc: Randy Dodgen <rdodgen@gmail.com>\nCc: Christoph Hellwig <hch@infradead.org>\nCc: Theodore Ts'o <tytso@mit.edu>\n\n---\n\nChanges in v2:\n - A bunch of cleanup and simplifications from Eryu.\n---\n tests/generic/451 | 73 +++++++++++++++++++++++++++++++++++++++++++++++++++\n tests/generic/451.out | 3 +++\n tests/generic/group | 1 +\n 3 files changed, 77 insertions(+)\n create mode 100755 tests/generic/451\n create mode 100644 tests/generic/451.out", "diff": "diff --git a/tests/generic/451 b/tests/generic/451\nnew file mode 100755\nindex 0000000..785c52e\n--- /dev/null\n+++ b/tests/generic/451\n@@ -0,0 +1,73 @@\n+#! /bin/bash\n+# FS QA Test 451\n+#\n+# This is a regression test for kernel patch:\n+# commit 42d4a99b09cb (\"ext4: fix fault handling when mounted with -o dax,ro\")\n+# created by Ross Zwisler <ross.zwisler@linux.intel.com>\n+#\n+#-----------------------------------------------------------------------\n+# Copyright (c) 2017 Intel Corporation.
