+Subject: [PATCH] vmcore-dmesg: Define _GNU_SOURCE
+
+loff_t is guarded with _GNU_SOURCE on some C library implementations
+e.g. musl since this type is not defined by POSIX. Define _GNU_SOURCE to
+include this define, it should help compiling on musl while nothing
+changes for glibc based systems since there _GNU_SOURCE is already
+defined
