Why This File Exists

Shared kernel service surface used by multiple subsystems, including helpers, cryptography, virtualization support, and async I/O infrastructure.

• Shared kernel service surface used by multiple subsystems, including helpers, cryptography, virtualization support, and async I/O infrastructure.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/io_uring_types.h

Detected Declarations

• struct io_uring_bpf_ops
• function io_unregister_bpf_ops

Annotated Snippet

struct io_uring_bpf_ops {
	int (*loop_step)(struct iou_ctx *, struct iou_loop_params *lp);

	__u32 ring_fd;
	void *priv;
};

#ifdef CONFIG_IO_URING_BPF_OPS
void io_unregister_bpf_ops(struct io_ring_ctx *ctx);
#else
static inline void io_unregister_bpf_ops(struct io_ring_ctx *ctx)
{
}
#endif

#endif /* IOU_BPF_OPS_H */

Annotation

• Immediate include surface: `linux/io_uring_types.h`.
• Detected declarations: `struct io_uring_bpf_ops`, `function io_unregister_bpf_ops`.
• Atlas domain: Kernel Services / io_uring.
• 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.
