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?
