+debugfs.c: the max length of debugfs argument is too short
+
+The max length of debugfs argument is 256 which is too short, the
+arguments are two paths, the PATH_MAX is 4096 according to
+/usr/include/linux/limits.h, so use BUFSIZ (which is 8192 on Linux
+systems), that's also what the ss library uses.
