Subject: [REVISED PULL REQUEST] md updates for 2.6.36
Hi Linus,
here is a revised pull request for md updates for 2.6.36.
To the previous patches (which are unchanged) it adds some work by
David Woodhouse which moves the RAID6 computations out of drivers/md/
and places them in /lib so they can be used by other code -
e.g. btrfs.
The RAID6 code is completely unchanged (it was already accessed under
the async-crypto interface so not changes are need to the API). Only
it's location and the fact that it can be a stand alone module
(rather than being in the same module as the rest of md/raid6) has
changed.
Thanks,
NeilBrown
