The changes > aren't _new_, but... Just checked linux-next, the first version that picked up the patches is 2018-11-19. The one dated 2018-10-19 does not have them.

I would understand if you prefer not to have them in the official tree at this time. -- blue skies, Martin. "Reality continues to ruin my life." - Calvin.
