The 4.15-rc1 kernel prepatch is out.
“So it’s been the usual two weeks of merge window, and rc1 is out.
And that normal time length is about the only thing usual about this
merge window. Because of the indiscriminate mass slaughter of turkeys
in the US last week, lots of people – including me – were on vacation.
That meant that I had asked for people to try to make the merge window
front-heavy, but it also meant that then during the second week I was
rather more strict than usual in what I pulled.”
