[SCSI] sd name space exhaustion causes system hang
Following a site power outage which re-enabled all the ports on my FC
switches, my system subsequently booted with far too many luns! I had
let it run hoping it would make multi-user. It didn't. :( It hung solid
after exhausting the last sd device, sdzzz, and attempting to create sdaaaa
and beyond. I was unable to get a dump.
Discovered using a 2.6.32.13 based system.
correct this by detecting when the last index is utilized and failing
the sd probe of the device. Patch applies to scsi-misc-2.6.
