Why This File Exists

Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.

• Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• media/videobuf2-v4l2.h
• linux/mm.h
• linux/refcount.h

Detected Declarations

• struct vb2_vmarea_handler

Annotated Snippet

struct vb2_vmarea_handler {
	refcount_t		*refcount;
	void			(*put)(void *arg);
	void			*arg;
};

extern const struct vm_operations_struct vb2_common_vm_ops;

struct frame_vector *vb2_create_framevec(unsigned long start,
					 unsigned long length,
					 bool write);
void vb2_destroy_framevec(struct frame_vector *vec);

Annotation

• Immediate include surface: `media/videobuf2-v4l2.h`, `linux/mm.h`, `linux/refcount.h`.
• Detected declarations: `struct vb2_vmarea_handler`.
• Atlas domain: Repository Root And Misc / include.
• 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.
