If you change the size in the header in your source tree, and then do a full make world and rebuild your kernel, I don't think you'll run into any problems. Oh, it's not inconceivable that some obscure port could be affected, but I'd be surprised. I'd recommend changing the field to an int (or maybe int32_t) rather than a long, though. A long on the Alpha is 64 bits, which is waaaay bigger than the reference count needs to be. A quick grep of the sources didn't show anything in userland that uses ifa_refcnt. So there shouldn't be any printf format mismatches from your change. (Changing a short to an int wouldn't cause any of them under any circumstances.) This is something that practically none of us can test, so you're in a unique position. :-) Your best bet is to change it yourself and try it. Assuming it works, follow-up your own PR with the patch and a statement that you've tested it without problems. It's more likely to get into the main source base if somebody has tested it under real-world conditions. John -- John Polstra jdp@polstra.com John D. Polstra & Co., Inc.
