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 😅 |
