Hi Zi,
Thanks a lot for your review and the valuable feedback! The issues you've pointed out are very helpful.

Regarding the logic where the PID is checked before the address ranges, 
that was an oversight on my part and I will fix it. 
I'll also add the test case for the iovec array size against IOV_MAX as you suggested.

And thank you for adding your Reviewed-by and Tested-by tags when i fix this.

I plan to collect all the review comments, revise the patches, and send out a new version 
with your tags included in the next 2-3 days.

Thanks again!



Best Regards,
Wang Lian
