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

• asm/mman.h
• asm-generic/hugetlb_encode.h
• linux/types.h

Detected Declarations

• struct cachestat_range
• struct cachestat

Annotated Snippet

struct cachestat_range {
	__u64 off;
	__u64 len;
};

struct cachestat {
	__u64 nr_cache;
	__u64 nr_dirty;
	__u64 nr_writeback;
	__u64 nr_evicted;
	__u64 nr_recently_evicted;
};

Annotation

• Immediate include surface: `asm/mman.h`, `asm-generic/hugetlb_encode.h`, `linux/types.h`.
• Detected declarations: `struct cachestat_range`, `struct cachestat`.
• 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.
