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

• linux/fscache.h

Detected Declarations

• function v9fs_cache_inode_get_cookie

Annotated Snippet

#ifndef _9P_CACHE_H
#define _9P_CACHE_H

#ifdef CONFIG_9P_FSCACHE
#include <linux/fscache.h>

extern int v9fs_cache_session_get_cookie(struct v9fs_session_info *v9ses,
					  const char *dev_name);

extern void v9fs_cache_inode_get_cookie(struct inode *inode);

#else /* CONFIG_9P_FSCACHE */

static inline void v9fs_cache_inode_get_cookie(struct inode *inode)
{
}

#endif /* CONFIG_9P_FSCACHE */
#endif /* _9P_CACHE_H */

Annotation

• Immediate include surface: `linux/fscache.h`.
• Detected declarations: `function v9fs_cache_inode_get_cookie`.
• Atlas domain: Core OS / VFS And Filesystem Core.
• 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.
