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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• xxhash.h

Detected Declarations

• struct sym_checksum
• struct checksum
• struct checksum

Annotated Snippet

struct sym_checksum {
	u64 addr;
	u64 checksum;
};

#ifdef BUILD_KLP

#include <xxhash.h>

struct checksum {
	XXH3_state_t *state;
	XXH64_hash_t checksum;
};

#else /* !BUILD_KLP */

struct checksum {};

#endif /* !BUILD_KLP */

#endif /* _OBJTOOL_CHECKSUM_TYPES_H */

Annotation

• Immediate include surface: `xxhash.h`.
• Detected declarations: `struct sym_checksum`, `struct checksum`, `struct checksum`.
• 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.
