+Subject: [PATCH 3/3] test_fs.c: Fix issue on 32-bit systems using btrfs
+
+On Fedora's build system, the build environment runs on btrfs. This
+revealed a bug in the test on i686 systems, where this comparison was
+being performed as a comparison of two signed integers, but the
+filesystem type of btrfs happens to use the higher-order bits, resulting
+in it appearing as a negative value.
