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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/module.h
• linux/kernel.h
• linux/string.h
• linux/nls.h
• linux/errno.h

Detected Declarations

• function uni2char
• function char2uni
• function init_nls_iso8859_4
• function exit_nls_iso8859_4
• module init init_nls_iso8859_4

Annotation

• Immediate include surface: `linux/module.h`, `linux/kernel.h`, `linux/string.h`, `linux/nls.h`, `linux/errno.h`.
• Detected declarations: `function uni2char`, `function char2uni`, `function init_nls_iso8859_4`, `function exit_nls_iso8859_4`, `module init init_nls_iso8859_4`.
• Atlas domain: Core OS / VFS And Filesystem Core.
• Implementation status: integration 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.
