Annotated Snippet

#include <bpf/bpf_helpers.h>

int get_set_sk_priority(void *ctx)
{
	int prio;

	/* Verify that context allows calling bpf_getsockopt and
	 * bpf_setsockopt by reading and writing back socket
	 * priority.
	 */

	if (bpf_getsockopt(ctx, SOL_SOCKET, SO_PRIORITY, &prio, sizeof(prio)))
		return 0;
	if (bpf_setsockopt(ctx, SOL_SOCKET, SO_PRIORITY, &prio, sizeof(prio)))

	return 1;

Annotation

• Immediate include surface: `sys/socket.h`, `bpf/bpf_helpers.h`.
• Detected declarations: `function get_set_sk_priority`.
• Atlas domain: Support Tooling And Documentation / tools.
• 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.
