The change to __virtnet_get_hw_stats() is a bugfix but the change to virtnet_get_hw_stats() was not a bugfix. I viewed this all as really one thing, because it's cleaning up the error codes which happens to fix a bug. It seems very related. At the same time, I can also see how people would disagree. I'm traveling until May 23. I can resend this. Probably as two patches for simpler review. regards, dan carpenter
