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 xoff_bitmap
• function xoff_bitmap_init
• function xoff_bitmap_destroy
• function xoff_bitmap_set
• function xoff_bitmap_walk

Annotated Snippet

	struct xbitmap64	offbitmap;

static inline void xoff_bitmap_destroy(struct xoff_bitmap *bitmap)

	xbitmap64_destroy(&bitmap->offbitmap);
}

static inline int xoff_bitmap_set(struct xoff_bitmap *bitmap,
		xfs_fileoff_t off, xfs_filblks_t len)

	return xbitmap64_set(&bitmap->offbitmap, off, len);
}

Annotation

• Detected declarations: `struct xoff_bitmap`, `function xoff_bitmap_init`, `function xoff_bitmap_destroy`, `function xoff_bitmap_set`, `function xoff_bitmap_walk`.
• 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.
