Hi,
I found a "funky" bug the other day with this driver; I was testing on a
RAID device of which I won't mention the vendor, but it had the habit of
returning QUEUE FULL when it's internal queue was full, with multiple
luns active that could even be on a lun which had exactly zero
outstanding IO already. The qlogic driver happily takes the number of
outstanding commands (0) and subtracts 1 from it to guestimate the
max... needless to say that didn't go down to well :-) Sounds like a
bound check would make sense here...
Greetings,
Arjan van de Ven
