itself.
What: /sys/kernel/btf/<module-name>
Date: Nov 2020
KernelVersion: 5.11
Contact: bpf@vger.kernel.org
Description:
Read-only binary attribute exposing kernel module's BTF type
information as an add-on to the kernel's BTF (/sys/kernel/btf/vmlinux).Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
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.
