Hi there, working at Google in the Android Linux Kernel team. I'll be writing test cases for recvmmsg(2). Can you "assign" this "issue" to me? (I couldn't).

Hello Ramon, just inform here you are working on the issue - like you did - and you can opt to send a patch to project maintainers (Cyril and Jan) through here or, preferably, on the mailing list.

@ramonpantin: thank you for expressing interest in taking this on! Unfortunately, the way GitHub is designed, issues can only be assigned to official contributors/maintainers. @rafaeldtinoco's suggestion is the right way to continue working on this item.

we already has sendmmsg01.c and recvmmsg01.c
