### AI overview

This Chinese-language series systematically explains eBPF's Linux kernel implementation, covering the BPF instruction set and registers, verifier algorithms, JIT compilation, map data structures and concurrency, helper type checking, BTF and CO-RE relocation, libbpf loading, trampolines, and sched_ext interfaces. It is aimed at engineers who want to understand eBPF kernel source code and build production BPF programs.
