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 an operation table; this is where Linux turns generic core objects into subsystem-specific behavior.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/efi.h

Detected Declarations

• struct efivarfs_mount_opts
• struct efivarfs_fs_info
• struct efi_variable
• struct efivar_entry

Annotated Snippet

extern const struct file_operations efivarfs_file_operations;
extern const struct inode_operations efivarfs_dir_inode_operations;
extern struct inode *efivarfs_get_inode(struct super_block *sb,
			const struct inode *dir, int mode, dev_t dev,
			bool is_removable);

Annotation

• Immediate include surface: `linux/efi.h`.
• Detected declarations: `struct efivarfs_mount_opts`, `struct efivarfs_fs_info`, `struct efi_variable`, `struct efivar_entry`.
• Atlas domain: Core OS / VFS And Filesystem Core.
• Implementation status: pattern 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.
