One thing I really hate about this is that it introduces two ptrace implementation by adding the new one without removing the old one. Given that's it's pretty much too later for the 2.6.33 cycle anyway I'd suggest you make sure the remaining two major architectures (arm and mips) get converted, and if the remaining minor architectures don't manage to get their homework done they're left without ptrace. The other thing is that this patchset really doesn't quite justify utrace. It's growing a lot more code without actually growing any useful functionality. What about all those other utrace killer features that have been promised for a long time? -- 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/
