generic/317 will fail because execvp(cmd) is executed without permission,
where cmd is '$here/src/lstat64 $file', which is called by
$here/src/nsexec -s -U -M "0 $qa_user_id 1000" -G "0 $qa_user_id 1000"\
$here/src/lstat64 $file
So, you will see following output:
From user_ns
...
+execvp: Permission denied
nsexec runs the instruction '$here/src/lstat64 $file' as a regular user,
the regular user may not have permission to access path in '$here'.
Actually, it has been fixed in 4818302fbf ("xfstests: generic/317 use
relative paths..."), which then been modified by b7cecbea22 ("fstests:
Add path $here before src/<file>").
Fixes: b7cecbea22 ("fstests: Add path $here before src/<file>")
