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.
- Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
- Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
- Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

- Immediate include surface: `linux/mm.h`, `linux/slab.h`, `linux/export.h`, `linux/balloon.h`.
- Detected declarations: `function balloon_page_insert`, `function balloon_page_finalize`, `function balloon_page_enqueue_one`, `function balloon_page_list_enqueue`, `function balloon_page_list_dequeue`, `function balloon_page_enqueue`, `function balloon_page_isolate`, `function balloon_page_putback`, `function balloon_page_migrate`, `function balloon_init`.
- Atlas domain: Core OS / Memory Management.
- Implementation status: integration implementation candidate.
- Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.
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.
