The powers that be, Linus in particular, are not fond of default

The default sizing is stupid as it basically makes RAID unusable out
of the box, I always have to fix that up, as well as a somewhat
reasonable chunk size for parity RAID to make it usable.  I'm also
pretty sure I complained about it at least once a while ago, but never
got a reply.
