Why This File Exists

Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.

• Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• xen/interface/xen.h

Detected Declarations

• struct callback_register
• struct callback_unregister

Annotated Snippet

struct callback_register {
	uint16_t type;
	uint16_t flags;
	xen_callback_t address;
};

/*
 * Unregister a callback.
 *
 * Not all callbacks can be unregistered. -EINVAL will be returned if
 * you attempt to unregister such a callback.
 */
#define CALLBACKOP_unregister              1
struct callback_unregister {
    uint16_t type;
    uint16_t _unused;
};

Annotation

• Immediate include surface: `xen/interface/xen.h`.
• Detected declarations: `struct callback_register`, `struct callback_unregister`.
• Atlas domain: Repository Root And Misc / include.
• 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.
