+This example is adapted from Meta's arena_list.c in the Linux kernel samples, with educational enhancements. It requires Linux kernel 6.9+ with BPF JIT support (`CONFIG_BPF_JIT=y`). BPF arena is not controlled by a separate `CONFIG_BPF_ARENA` option. Complete source code is available in the tutorial repository.
