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/spinlock.h

Detected Declarations

• struct gfs2_sbd

Annotated Snippet

#ifndef __SYS_DOT_H__
#define __SYS_DOT_H__

#include <linux/spinlock.h>
struct gfs2_sbd;

int gfs2_sys_fs_add(struct gfs2_sbd *sdp);
void gfs2_sys_fs_del(struct gfs2_sbd *sdp);

int gfs2_sys_init(void);
void gfs2_sys_uninit(void);

int gfs2_recover_set(struct gfs2_sbd *sdp, unsigned jid);

#endif /* __SYS_DOT_H__ */

Annotation

• Immediate include surface: `linux/spinlock.h`.
• Detected declarations: `struct gfs2_sbd`.
• 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.
