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/types.h

Detected Declarations

• struct vmcoredd_header
• enum hwerr_error_type

Annotated Snippet

	__u32 n_namesz; /* Name size */
	__u32 n_descsz; /* Content size */
	__u32 n_type;   /* NT_VMCOREDD */
	__u8 name[8];   /* LINUX\0\0\0 */
	__u8 dump_name[VMCOREDD_MAX_NAME_BYTES]; /* Device dump's name */
};

enum hwerr_error_type {
	HWERR_RECOV_CPU,
	HWERR_RECOV_MEMORY,
	HWERR_RECOV_PCI,
	HWERR_RECOV_CXL,
	HWERR_RECOV_OTHERS,

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct vmcoredd_header`, `enum hwerr_error_type`.
• 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.
