Hi Linus,
please pull some md fixes for 2.6.32 as described below.
The main issues related to:
- The recently merged hardware offload for RAID6 calculations, which
didn't handle the DDF style properly, and
- The less recently added reshaping code that allows a RAID5 to be
reshaped to have fewer devices. Restarting such an array if it
was shutdown during the reshape did not work.
Also we remove a build-time dependency on perl.
Thanks,
NeilBrown
