+         Choose Y or M here to include support for mounting the
+         experimental Ceph distributed file system.  Ceph is an extremely
+         scalable file system designed to provide high performance,
+         reliable access to petabytes of storage.

+       default n
+       help
+         If you say Y here, debug output will include a filename and
+         line to aid debugging.  This icnreases kernel size and slows
+         execution slightly when debug call sites are enabled (e.g.,
+         via CONFIG_DYNAMIC_DEBUG).

+         If unsure, say N.
