What would be good is if some effort could be made by the utrace- interested parties to make the transition to utrace much less painful. For instance, I quite like the getregs/setregs abstractions, and it looks like these *could* be self-contained in a single patch. It would be nice if we could move architectures over to this one a time. Once that's in, that's one chunk of utrace merged. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: - 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/
