Why This File Exists

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

• Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.
• Allocates kernel memory; connect allocation flags and lifetime to context constraints.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• bpf_arena_common.h

Detected Declarations

• function bpf_alloc
• function bpf_free
• function bpf_alloc
• function bpf_free

Annotated Snippet

static inline void __arena* bpf_alloc(unsigned int size) { return NULL; }
static inline void bpf_free(void __arena *addr) {}
#endif

Annotation

• Immediate include surface: `bpf_arena_common.h`.
• Detected declarations: `function bpf_alloc`, `function bpf_free`, `function bpf_alloc`, `function bpf_free`.
• 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.
