You could have editorialized this title to:

Rebasing a Linux Kernel Branch that’s Two Years Old and 9k Commits Deep

…but you would have had thousands of us running to the bathroom to revisit our last meal.

What a Herculean effort by these two engineers. When your role is to track down fellow employees from completely different teams and crack the, er, carrot to get them to update their patch from two years ago, you can get very tired very quickly.

I’m sure the hardware driver modules are fairly self contained but things like the userspace QoS patch could be pretty hairy. The kind of thing where, for upstream, you’d spend 90% of your time landing a framework just to even be able to implement your feature with the final 10% patch.

Oof. Bravo.
