Patches has been sent and acked, so I already have my answer, but just to double
check, these are not just fixes which normally rc3 should target, there are data
path updates and performance improvements.

Can you please confirm you want these patches in at rc3 phase?
I will wait for your explicit approval before getting them.

Thanks,
ferruh
