I had asked a couple of cancel-safe queue questions a while ago. Mark
Cariddi pointed me at some papers, which I read, but I still have a question,
so I thought I’d give it one more shot.
In his WDM book (2nd Ed.), Walter Oney refers to a subtle race condition
in even the best systems that arises from a coincidence in IRP pointer
values. I think he means that the flaw was present in the StartIo /
global cancel lock scheme; I’d still be curious to know what flaw he
was referring to, though. Why doesn’t the CSQ library suffer from this
flaw?
Thanks.
