I'll deal with them and appreciate the effort you've done reviewing the code. I'm just busy doing revamping sgx_page_cache.c based on the feedback I got from Dave Hansen. After I'm done with that I'll response to those emails. I'm sorry about the latency. I gave some feedback to the tglx's original response. If something is lacking, please ping me. /Jarkko -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
