Yes I know that, sorry my wording in the backport request was not
quite optimal to understand. I knew it was already included in 7.0.12,
6.18.35 and 6.12.93. When looking why it was not picked for the older
series I noticed might just have been the context change, which I
tested down to 6.1.y and proposed the adjusted backported commit.

I realize that the commit for 6.6.y needs to be as well slightly
different.

What I have *not* done was to test if it goes clean as well back to
5.15 and 5.10. It will need likely more work as there is no
net_zcopy_get() in 5.10.y.

Sasha, do you want me to send as well an explicit 6.6.y one? Or will
you pick the change already for 6.6.y and 6.1.y? 

Regards,
Salvatore
