Linux 5.3 rc1

It's been two weeks, and the merge window is over, and Linux 5.3-rc1is tagged and pushed out.This is a pretty big release, judging by the commit count. Not thebiggest ever (that honor still goes to 4.9-rc1, which wasexceptionally big), and we've had a couple of comparable ones (4.12,4.15 and 4.19 were also big merge windows), but it's definitely upthere.The merge window also started out pretty painfully, with me hitting acouple of bugs in the first couple of days. That's never a good sign,since I don't tend to do anything particularly odd, and if I hit bugsit means code wasn't tested well enough. In one case it was due to meusing a simplified configuration that hadn't been tested, and causedan odd issue to show up - it happens. But in the other case, it reallywas code that was too recent and too rough and hadn't baked enough.The first got fixed, the second just got reverted.Anyway, despite the rocky start, and the big size, things mostlysmoothed out towards the end of the merge window. And there's a lot tolike in 5.3. Too much to do the shortlog with individual commits, ofcourse, so appended is the usual "mergelog" of people I merged fromand a one-liner very high-level "what got merged". For more detail,you should go check the git tree.As always: the people credited below are just the people I pull from,there's about 1600 individual developers (for 12500+ non-mergecommits) in this merge window.Go test,            Linus
