Finally it will be, but currently the code base is too far. I would like to implement it on current code for avoiding break anything, but refactoring afterwards. I think current fetch function implementation may be too heavy with retpoline. I would like to reimplement it with eBPF :) Thank you, > > -- Steve -- Masami Hiramatsu
