So as already mentioned a couple of times in some of the relevant threads, this last week wasn't entirely painless, and 4.18 ended up being one of those releases that gets an extra week of rc testing before release.
The original impetus for this was the continued VM worries - although it looks like we finally root-caused all the issues and got it all in shape on Wednesday. Still, that is somewhat late, and merits another rc for final testing.
That said, if it had been _only_ that silly VM issue that turned out to not be so annoying as it could have been, I might have reconsidered and done a final release anyway, but we had some last-minute networking noise too, and there's actually a pending (old) VFS issue too. So while I may prefer to keep our regular release cadence, but this time around we are just going to see that extra week.
I realize that this may mess with people who had planned for the merge window to start tomorrow - particularly the Europeans where August is often peak vacation time. Never fear, you can send me your merge window pull request next week as planned, and I'll just sit on it for the extra week. So go off on your planned vacations.
Anyway, appended is the shortlog for the changes during the last week - and despite the extra week, it's not really horrible. Over a quarter of the patch is tooling updates, with some testing and tooling updates for perf, turbostat and bpf.
On the actual kernel side, most of the (small) changes were to drivers, with network drivers leading the way. There's also some core networking changes, along with some minor arch updates.
And we've got the VM fixes. and misc noise elsewhere. See below for the shortlog, or delve into the git repo for the nitty-gritty details.
