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.

Hmmm, if it's only used by cam, why isn't it in cam/ rather than kern/ ?
