This suggests we can change it given a sufficiently good reason. debugfs isn't a good idea since ordinary systems won't (or shouldn't) have it mounted. In case I wasn't clear: some of these statistics _are_ useful to administrators with sufficient RAID knowledge. For example, if "out of stripes" is large and you have lots of memory, increasing stripe_cache_size will likely be useful.
