Benny hi, thanks.
You will need all the other ORE patches. But they should be
in Linus tree before the 3.3-rc1 so you might just get them
from there.
And this below! With out this fix, the objlayout driver hits
a BUG_ON. Do you think I should check all raid parameters
at client so a BAD server will not crash a client?
Thanks
Boaz
