They’re gathering firewood….and petrol tankers :-)
Actually I too was pretty surprised to see it committed.

Personally, Noooo! :-)  This sounds like backports territory.  And I’m back to that idea of dropping the kmod package and introducing cake via a kernel patch for openwrt.   *shudder*

>> 4.19 isn’t even released yet, so most people, including Openwrt, get cake via our 'out of tree’ repositories.  This is also a good idea from a point of view of testing.  I appreciate the latest changes are of ‘one line’ type variety and so mostly harmless but ideally it should at least be in our own out of tree repo’s first/at the same time.

Lord no, not the bikeshed!  I was more thinking of including the two new keywords that had been introduced….. not going wild   :-)
