DELL Universal Xport no attach blacklist

DELL Universal Xport no attach blacklist

[Thomas Witzel]

I have been getting tons of Buffer I/O errors on the Universal Xport
devices of my DELL MD3000. This can be managed by not attaching
them....
Can you please add the DELL Universal Xport to the no attach list in
scsi_devinfo.c ? I'm not sure how to submit a patch because I don't
know which version of the kernel the patch should be against, but I
know its not yet in the newest Linus kernel. I want this line added
please,

I'll add it via cut and paste.

For future reference, you can submit the patch yourself too if you
follow Documentation/SubmittingPatches.  The only real problem with the
above is that there's no signoff line, it's not tree relative and your
mailer seems to have converted tabs to spaces (we have a separate file
Documentation/email-clients.txt to try to address this, but it's not
comprehensive, there being more broken email clients out there than we
can document fixes for).
