[$] 4.18 Merge window, part 2

By the time that Linus Torvalds released 4.18-rc1 and closed the merge window for this development cycle, 11,594 non-merge changesets hadfound their way into the mainline kernel repository. Nearly 4,500 of thosewere pulled after last week's summary waswritten. Thus, in terms of commit traffic, 4.18 looks to be quite similarto its predecessors. As usual, the entry of significant new features hasslowed toward the end of the merge window, but there are still someimportant changes on the list.
