So, is this how the Linux community is now dysfunctional? Someone sends a patch. Thomas reviews, says it's a good idea and provides some feedback. Author asks questions, gets ignored. Author sends a patch taking in to account that previous feedback. Someone else replies, contradicting the previous feedback. Nothing else happens. What a bloody sorry state of affairs. Makes me wonder what the point of trying to contribute to the Linux kernel outside of the areas I actually maintain anymore is. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
