If you have gone this far you might as well point towards the bullshit article that published it

I think he is going to pull a "nobody knows what I do until I don't do it", betting that 4.19 will fall apart on people.
I am hoping it is the best kernel ever.

is it time for the floss communities to stop obsessing about linus and focus on what gregkh eats for breakfast / uses to edit text instead?

nope, linus is back for a little while longer. (and probably for some time to come. but at least now we have experience with gkh as the lead dev.)

oh im well aware that gkh is a nightmare, i dont like torvalds but i will probably miss him when he steps down for real someday.
