[PULL REQUEST] md updates for 2.6.38

Hi Linus,
here are a few more md updates.
most are bugs in relatively recent code.
This is small "enhancement" in there in that raid1->raid0 conversion is now
possible. That is largely just an extension to the other conversions that
were added in the merge window.

One fix (from Chris Mason) is tagged for -stable.

Thanks,
NeilBrown
