As promised by Linus, he has just released kernel 4.20 before Christmas. It’s not an LTS release (4.19 is), but it brings some significant changes and improvements.
Let’s face it, last week wasn’t quite as quiet as I would have hoped for, but there really doesn’t seem to be any point to delay 4.20 because everybody is already taking a break.
Some of the new features include:
- network flow dissectors in BPF
- the taprio traffic scheduler
- peer-to-peer DMA support in the PCI layer
- C-SKY architecture support
- pressure-stall instrumentation mechanism
- XArray data structure
