Annotation
- Immediate include surface: `vmlinux.h`, `bpf/bpf_helpers.h`, `bpf/bpf_tracing.h`, `bpf/bpf_core_read.h`, `bpf_misc.h`.
- Detected declarations: `function handle_kprobe`, `function handle_kretprobe`, `function handle_uprobe`, `function handle_uretprobe`, `function handle_uprobe_byname`.
- Atlas domain: Support Tooling And Documentation / tools.
- Implementation status: source implementation candidate.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
