#define _TOOLS_LINUX_ALIGN_H

#include <uapi/linux/const.h>

#define ALIGN(x, a)		__ALIGN_KERNEL((x), (a))
#define ALIGN_DOWN(x, a)	__ALIGN_KERNEL((x) - ((a) - 1), (a))

#endif /* _TOOLS_LINUX_ALIGN_H */

Annotation

• Immediate include surface: `uapi/linux/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.
