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

• linux/proc_fs.h

Detected Declarations

• struct rpc_stat
• struct svc_stat
• struct net
• function rpc_proc_init
• function rpc_proc_exit
• function rpc_proc_unregister
• function svc_proc_unregister

Annotation

• Immediate include surface: `linux/proc_fs.h`.
• Detected declarations: `struct rpc_stat`, `struct svc_stat`, `struct net`, `function rpc_proc_init`, `function rpc_proc_exit`, `function rpc_proc_unregister`, `function svc_proc_unregister`.
• Atlas domain: Core OS / Core Kernel Interface.
• 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.
