Does the current arm ptrace code support single stepping in kernelspace? If yes we absolutely need to continue to support it. > I'd also like to see utrace become *optional* > for architectures to support, rather than as it currently stands as > a *mandatory* requirement when merged. No way we'd keep both the old ptrace mess and utrace in the same tree. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
