Oh no, I don't think anyone will say it's unnecessary! I agree the A64_FP-related change is a good idea, so stack unwinding works. How about splitting this into two patches? One for the BPF-related bug, and another for A64 FP-handling. Thanks again for tracking this down and improving things overall for arm64 :) > > Thanks, > Yang > > -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
