Subject: [PULL REQUEST] md updates for 2.6.31


Hi Linus,
 here is the merge-window pull request for md.

 The only real functional change is that we now support non-power-of-2
 chunk sizes in raid0.
 Apart from that there is a lot of simplification and clean up in
 raid0 and linear, some minor refactorisation, and assorted bug fixes.

thanks,
NeilBrown
