Annotated Snippet

#ifndef __VDSO_BITS_H
#define __VDSO_BITS_H

#include <vdso/const.h>

#define BIT(nr)			(UL(1) << (nr))
#define BIT_ULL(nr)		(ULL(1) << (nr))

#endif	/* __VDSO_BITS_H */

Annotation

• Immediate include surface: `vdso/const.h`.
• 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.
