- What I did

Enabled CONFIG_PSI for 5.15 kernels. PSI https://facebookmicrosites.github.io/psi/docs/overview enables cpu/memory/io.pressure files in cgroupv2 (already enabled) as well as /proc/pressure that is useful for analyzing the performance of applications and the system.

- How I did it

- How to verify it

Build kernel and check /proc/pressure.

- Description for the changelog

- Enable CONFIG_PSI in 5.15.x kernel configuration

- A picture of a cute animal (not mandatory but encouraged)

FYI I am also making an update to the latest kernel versions in #3919, with the intention to enable BTF after that also.

@errordeveloper This PR does not do BTF. Maybe you meant #3755

I also need 6.1 (at least) https://github.com/linuxkit/linuxkit/compare/master...tonistiigi:linuxkit:6.1-kernel?expand=1 . Unless somebody beats me to it I can open/rebase it after #3919 is in.

Yeah, I was just saying, cause I noticed that BTF PR too.

I am not bracing it for 6.1 just yet, cause I had more trouble then I had anticipated bumping up the patch version 😅
