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 posix_acl_xattr_entry
• struct posix_acl_xattr_header

Annotated Snippet

struct posix_acl_xattr_entry {
	__le16			e_tag;
	__le16			e_perm;
	__le32			e_id;
};

struct posix_acl_xattr_header {
	__le32			a_version;
};

#endif	/* __UAPI_POSIX_ACL_XATTR_H */

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct posix_acl_xattr_entry`, `struct posix_acl_xattr_header`.
• 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.
