Instead of having multiple approaches, I'd strongly prefer that we converge on a single in-tree approach that works for everybody. (Whether that will be source-based like klp-convert or binary-based like kpatch-build, I don't know.) BTW, what is bin-diff?

IMO, klp-convert will only be useful if we have a realistic strategy for dealing with GCC optimizations. So I'd say we should follow through on that with the compiler folks before spending too much more time on it. -- Josh -- To unsubscribe from this list: send the line "unsubscribe live-patching" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
