To protect linux-next from brand new material. It serves no other purpose. Almost. I'll very occasionally use it for short-term not-for-upstream playthings. > Generally anything submitted early in the cycle is expected to land in the cycle > unless there's significant adverse review or other reasons it can't be taken. Yup. Don't want anything in mm.git which isn't expected to be upstreamed in the next merge window. Nowadays I'm reluctant to add anything which hasn't had a decent scan from reviewers. If it's something I'd particularly like to get upstreamed I'll very occasionally add it early, to help push it along.
