Perhaps these developers should rethink the design and protocols of their apps - or pay the price for a stupid design which relies on heavy IPC traffic (and usually - sooner or later - heavy network traffic). Or - at least - deliver a (technical!) proof why this isn't feasible. The case of "patching the kernel to lie about the kernel's command line" just because some ill-designed user-space daemon misused it" was bad enough and the above smells quite similarly. Kind regards, Bernd -- "I dislike type abstraction if it has no real reason. And saving on typing is not a good reason - if your typing speed is the main issue when you're coding, you're doing something seriously wrong." - Linus Torvalds -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
