[Disksim-users] Queue Structure

[YipKei Kwok]

Hi,

Is there any developer's guide for disksim which talks about the I/O
queue structure used for scheduling.

In the file disksim_ioqueue.c, the queue structure is not that
understandable. For example, the iob structure pointed by queue->list
is not the head of the queue but queue->list->next. Also, sometimes,
but not always, the next pointers of some iob structures on a queue is
actually pointing back to itself.

Can anyone explain the queue structure used in Disksim, especially in
the file disksim_ioqueue.c? Or, even better, is there any developer's
manual for disksim?

Thank you very much!

Regards,
Yipkei
