Why This File Exists

Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.

• Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.

Dependency Surface

• uapi/linux/personality.h

Detected Declarations

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

Annotated Snippet

#ifndef _LINUX_PERSONALITY_H
#define _LINUX_PERSONALITY_H

#include <uapi/linux/personality.h>

/*
 * Return the base personality without flags.
 */
#define personality(pers)	(pers & PER_MASK)

/*
 * Change personality of the currently running process.
 */
#define set_personality(pers)	(current->personality = (pers))

#endif /* _LINUX_PERSONALITY_H */

Annotation

• Immediate include surface: `uapi/linux/personality.h`.
• Atlas domain: Core OS / Core Kernel Interface.
• 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.
