This change is a precursor to adding new features to the I/O stack. It is mostly mechanical. If you are running current on a raid or scsi card, especially if it is a lesser used one, I would really like you to apply this patch and report back any problems. If it works you should notice nothing. If it doesn't work you will probably panic immediately on I/O or otherwise no I/O will happen. I haven't tested it yet. My only comment from reading it though would be to make subr_busdma.c be dependent on cam, since it can only used from cam. We've grown sloppy about noting these dependencies in the tree...
