I have rediffed the patch against 2.6.13-rc5, done a couple of cosmetic
cleanups, and run some tests. Brian King has acknowledged that it fixes the
problems he has seen. Seems mature enough for inclusion into 2.6.14 (or
later)?
Nate's explanation of the changes:
I've attached patches against 2.6.13rc2. These are basically identical
to my earlier patches, as I found that all issues I'd seen in earlier
kernels still existed in this kernel.
To summarize, the changes are: (more details in my original email)
- add a kref to the scsi_tape structure, and associate reference
counting stuff
- set sr_request->end_io = blk_end_sync_rq so we get notified when an IO
is rejected when the device goes away
- check rq_status when IOs complete, else we don't know that IOs
rejected for a dead device in fact did not complete
- change last_SRpnt so it's set before an async IO is issued (in case
st_sleep_done is bypassed)
- fix a bogus use of last_SRpnt in st_chk_result

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
