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 xdab_bitmap
• function xdab_bitmap_init
• function xdab_bitmap_destroy
• function xdab_bitmap_set
• function xdab_bitmap_test

Annotated Snippet

	struct xbitmap32	dabitmap;
};

static inline void xdab_bitmap_init(struct xdab_bitmap *bitmap)
{
	xbitmap32_init(&bitmap->dabitmap);
}

static inline void xdab_bitmap_destroy(struct xdab_bitmap *bitmap)
{
	xbitmap32_destroy(&bitmap->dabitmap);
}

static inline int xdab_bitmap_set(struct xdab_bitmap *bitmap,
		xfs_dablk_t dabno, xfs_extlen_t len)
{
	return xbitmap32_set(&bitmap->dabitmap, dabno, len);
}

static inline bool xdab_bitmap_test(struct xdab_bitmap *bitmap,
		xfs_dablk_t dabno, xfs_extlen_t *len)
{
	return xbitmap32_test(&bitmap->dabitmap, dabno, len);

Annotation

• Detected declarations: `struct xdab_bitmap`, `function xdab_bitmap_init`, `function xdab_bitmap_destroy`, `function xdab_bitmap_set`, `function xdab_bitmap_test`.
• 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.
