This is not about C++, it's about plain old fashioned C, which has been the preferred kernel programming language for decades. I have no idea where you've got the idea that LinusW's commit has anything to do with C++. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
