I previously posted a patch to linux-scsi for scsi host and scsi device
ref count cleanups. The thread is available here:
http://marc.theaimsgroup.com/?t=105770318200001&r=1&w=2

I have updated the patch with comments, but still want to finish a change
to scsi_free_sdev and do some testing before I send it out again.

I do not run devfs currently so I have not seen the issue related to
devfs.
