cluster_limit   - no longer used, will be going away
debug           - hmm, maybe should be conditional, turns on some debug
                  tracing if the kernel has the correct code built in, which
                  it usually does not.
flush_age       - Age in milliseconds that a metadata buffer has to have to
                  be flushed.
flush_int       - how often we look for metadata to flush - in milliseconds
max_dio_pages   - the maximum number of pages in a direct I/O request which
                  will be locked down at once. If a user request is larger
                  than this then it will be split up into chunks.

So only three of them really mean anything now.
