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

• No C-style include directives detected by the generator.

Detected Declarations

• struct xchk_xattr_buf

Annotated Snippet

	unsigned long		*freemap;

	/* Memory buffer used to hold salvaged xattr names. */
	unsigned char		*name;

	/* Memory buffer used to extract xattr values. */
	void			*value;
	size_t			value_sz;
};

bool xchk_xattr_set_map(struct xfs_scrub *sc, unsigned long *map,

Annotation

• Detected declarations: `struct xchk_xattr_buf`.
• Atlas domain: Core OS / VFS And Filesystem Core.
• 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.
