+Subject: [PATCH] memfd-wrappers: only define memfd_create() if not already
+ defined
+
+glibc 2.27 is to be released soon, and it will provide memfd_create().
+If glibc provides the function, we must not define it ourselves,
+otherwise building fails due to conflict between the two implementations
+of the same function.
+
