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

Dependency Surface

• linux/ioctl.h
• linux/types.h

Detected Declarations

• struct nsm_iovec
• struct nsm_raw

Annotated Snippet

struct nsm_iovec {
	__u64 addr; /* Virtual address of target buffer */
	__u64 len;  /* Length of target buffer */
};

/* Raw NSM message. Only available with CAP_SYS_ADMIN. */
struct nsm_raw {
	/* Request from user */
	struct nsm_iovec request;
	/* Response to user */
	struct nsm_iovec response;
};
#define NSM_IOCTL_RAW		_IOWR(NSM_MAGIC, 0x0, struct nsm_raw)

#endif /* __UAPI_LINUX_NSM_H */

Annotation

• Immediate include surface: `linux/ioctl.h`, `linux/types.h`.
• Detected declarations: `struct nsm_iovec`, `struct nsm_raw`.
• 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.
