Sadly, no. I've got a git repository setup at kernel.org,
but so far failed to do anything with it.
Real life intercepting as per normal.

But on the good side I have the patchset cleaned up
to avoid the contested SCSI update.
IE the megasas emulation is now using the 'standard'
SCSI callback mechanism.

I see to have the patchset pushed to kernel.org
and will send a pointer then.

Cheers,

Hannes
