+    Explicitly make testcase variable for sys-copy_file_range undefined.
+    
+    On some systems an extra warning could occur when a variable in
+    the memcheck/tests/linux/sys-copy_file_range testcase was undefined,
+    but (accidentially) pointed to known bad memory. Fix by defining the
+    variable as 0, but then marking it explicitly undefined using memcheck
+    VALGRIND_MAKE_MEM_UNDEFINED.
+    
+    Followup for https://bugs.kde.org/show_bug.cgi?id=407218

+    Fix memcheck/tests/linux/sys-copy_file_range open call (mode).
+    
+    sys-copy_file_range.c calls open with O_CREAT flag and so must provide
+    a mode argument. valgrind memcheck actually caught this ommission on
+    some arches (fedora rawhide i686 specifically).
+    
+    This is a small additional fixup for
+    https://bugs.kde.org/show_bug.cgi?id=407218
