Yes, that's what I meant. Note that it won't get merged into 4.19: the merge window for that was after the 4.18 release and no new features are getting merged for 4.19 that have not made it into 4.19-rc1 already. Getting your code into linux-next now is the prerequisite for you sending a pull request during the 4.20 window. Arnd
