mdadm patch for experimental

[Aarno Aukia]

Hello Debian mdadm maintainer, madduck,

I backported mdadm 3.1.1 to lenny without any problems, but there is a  
bug in raid5->raid6 reshaping (bug: http://neil.brown.name/blog/20090817000931-027 
, patch: http://neil.brown.name/blog/20090817000931-028) that requires  
patching. Would it be possible to incorporate this and/or move to the  
developers 3.1.2 ?

Thanks and regards,
Aarno
