Kernel 4.17 rebase plans

[Justin Forbes]

While the 4.17 kernel was released almost 2 weeks ago, I wanted to get
through the 4.17 test day and see how things looked before coming up
with a definitive schedule.  Things went really well, and I expect F28
will get 4.17.2 or 4.17.3 into updates-testing next week.  F27 will
follow shortly after,  though it should still be in the June
timeframe.

Thanks,
Justin
