Kernel prepatch 5.2-rc1

Linus has released the 5.2-rc1 kernelprepatch and closed the merge window for this development cycle."Nothing particularly odd going on this merge window. I had sometravel in the middle of it, but to offset that I had a new fastertest-build setup, and most of the pull requests came in early (thank you)so my travels didn't actually end up affecting the merge window all thatmuch."
