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.
