Detected Declarations

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

Annotated Snippet

# SPDX-License-Identifier: GPL-2.0-only
config EFIVAR_FS
	tristate "EFI Variable filesystem"
	depends on EFI
	default m
	help
	  efivarfs is a replacement filesystem for the old EFI
	  variable support via sysfs, as it doesn't suffer from the
	  same 1024-byte variable size limit.

	  To compile this file system support as a module, choose M
	  here. The module will be called efivarfs.

	  If unsure, say N.

Annotation

• Atlas domain: Core OS / VFS And Filesystem Core.
• Implementation status: atlas-only.

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.
