Neil, do you agree? I'm happy to take the SSSE3 RAID-6 patches as they only affect lib/raid6, but I felt that this one - being purely in arch/x86 - should probably go via the x86 tree. However I'm flexible and if you (collectively) are happy with these patches going in through my tree, I'll do that. Thanks, NeilBrown > > However, > > Acked-by: H.
