Yeah, tweaked a few things based on your comments.

The SCSI patches depend on the block layer ditto (topology parameters
need to be present, etc.).
Also, we always do it this way so we can get the block layer changes in
during the merge window and then add the SCSI bits to the post-merge
tree.

Interesting, please do. I've only tested on SAS and FC...
