Hi Tejun,

    I did this work to replace sg chaining.  The current chaining code gives 
us longer sgs, and (if used carefully) the ability to append in some 
circumstances.  But it's clumsy, and we can do better.  This is my attempt.

    I understand that people are experiencing whiplash from the idea of 
another change just after the sg chaining changes which have already gone in.  

    At the very least, I think I'll have to come up with a better transition 
plan for SCSI drivers, rather than trying to convert them all at once... In 
theory, sg chaining can be done through the sg ring arrays, but that's pretty 
horrible.

Cheers,
Rusty.
