Dependency Surface

• No C-style include directives detected by the generator.

Detected Declarations

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

Annotated Snippet

	depends on BLOCK
	select BUFFER_HEAD
	help
	  EFS is an older file system used for non-ISO9660 CD-ROMs and hard
	  disk partitions by SGI's IRIX operating system (IRIX 6.0 and newer
	  uses the XFS file system for hard disk partitions however).

	  This implementation only offers read-only access. If you don't know
	  what all this is about, it's safe to say N. For more information
	  about EFS see its home page at <http://aeschi.ch.eu.org/efs/>.

	  To compile the EFS file system support as a module, choose M here: the
	  module will be called efs.

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.
