I don't know how the gatekeepers feel about this recent spate of
patches, but it seems like a valuable and overdue effort. Thanks.

I think it would be more correct, and still portable, to use long
instead of int to represent pointers. I don't know it C mandates it,
but I think the wide-spread convention is that longs are at least as big
as pointers, while the size of ints vary more widely. So this would
lead to code like this:
afsi_log("osi_LogCreate log addr %lx", (long)afsd_logp);
