We have more changes in that area coming in. Ok, thanks for the heads-up. I'll try a merge or rebase to see how this can be handled. If both the drivers/net and drivers/media get picked up for 5.14, maybe the rebased patches can go through -mm on top, along with the final removal of compat_alloc_user_space()/copy_in_user(). If not, I suppose these four patches can also wait another release. Arnd
