Yes, you can already see the beginnings in the -mm tree.
Jens is maintaining a block tree with this in here:
http://www.kernel.org/git/?p=linux/kernel/git/axboe/linux-2.6-block.git;a=shortlog;h=rq-map
And I have a scsi-block-2.6 tree based off this here:
http://www.kernel.org/git/?p=linux/kernel/git/jejb/scsi-block-2.6.git;a=summary
The missing (and frankly really nasty) pieces are pulling all the sg
handling out of sg and st, but fortunately Mike Christie is working on
that.
