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

• linux/spinlock.h

Detected Declarations

• struct lock_class_key
• function lockdep_set_class

Annotated Snippet

struct lock_class_key {
	unsigned int a;
};

static inline void lockdep_set_class(spinlock_t *lock,
					struct lock_class_key *key)
{
}

extern int lockdep_is_held(const void *);
#endif /* _LINUX_LOCKDEP_H */

Annotation

• Immediate include surface: `linux/spinlock.h`.
• Detected declarations: `struct lock_class_key`, `function lockdep_set_class`.
• 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.
