No. This thread is proposing an ABI. This means that, if the ABI ends up in Linus's kernel, then it has to be supported forever. Now is the time to find and fix any issues with it before they become much harder to fix. This ABI is especially tricky because programs will use it even if they don't explicitly try to. So just adding the ABI may break existing assumptions that are relevant to security or correctness. --Andy -- 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/
