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 an operation table; this is where Linux turns generic core objects into subsystem-specific behavior.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

• linux/workqueue.h
• linux/scatterlist.h
• linux/device.h

Annotation

• Immediate include surface: `linux/workqueue.h`, `linux/scatterlist.h`, `linux/device.h`.
• Detected declarations: `struct ms_status_register`, `struct ms_id_register`, `struct ms_param_register`, `struct ms_extra_data_register`, `struct ms_register`, `struct mspro_param_register`, `struct mspro_io_info_register`, `struct mspro_io_func_register`, `struct mspro_io_cmd_register`, `struct mspro_register`.
• Atlas domain: Core OS / Core Kernel Interface.
• Implementation status: pattern 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.
