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 xfs_fid64

Annotated Snippet

struct xfs_fid64 {
	u64 ino;
	u32 gen;
	u64 parent_ino;
	u32 parent_gen;
} __attribute__((packed));

/* This flag goes on the wire.  Don't play with it. */
#define XFS_FILEID_TYPE_64FLAG	0x80	/* NFS fileid has 64bit inodes */

struct inode *xfs_nfs_get_inode(struct super_block *sb, u64 ino, u32 gen);

#endif	/* __XFS_EXPORT_H__ */

Annotation

• Detected declarations: `struct xfs_fid64`.
• 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.
