The 7.3-rc6 kernel prepatch is out fortesting. Linus said:

Next week might look a bit different: we've got the annualmaintainer summit and the Linux plumbers conference going on , soI'll be on the road, as will a number of other maintainers. Thatmay or may not end up changing the stats for -rc7. But it'sunlikely to affect the release schedule, although the fact that Ihave my yearly family vacation the week after that might make thenext merge window a bit wonky.
