James? what's up?

I sent you, what is for me a very important fix, also targeted for stable
which is a one liner. I don't see it below. Do you plan on another scsi-fixes
batch?

If not than please send me your ack and I can push it through the exofs tree
since the most affected systems by this is any objects cluster like exofs+pnfs
type systems.

Thanks
