Hello there! In v1 and v2, I showed simple proof of concept of lockless cache. After some discussions, it turns out that there are some issues to solve. It will take some to solve them. I made git repository on github to share its progress: https://github.com/hygoni/linux.git This is based on v5.15-rc2, and the main branch will be 'lockless_cache'. There's *nothing* in the repo now and will be updated randomly. hopefully every 1-3 days, or every week. (note that I'm not full time kernel developer. it's hobby.) I'll make use of 'issues' and 'discussions' tab (github feature to track issues and discussions). You can join if you're interested. Thank you for your interest on this project! -- Hyeonggon
