Annotated Snippet

#!/bin/bash

TC="$1"; shift
ETH="$1"; shift

# The taprio architecture changes the admin schedule from a hrtimer and not
# from process context, so we need to wait in order to make sure that any
# schedule change actually took place.
while :; do
	has_admin="$($TC -j qdisc show dev $ETH root | jq '.[].options | has("admin")')"
	if [ "$has_admin" = "false" ]; then
		break;

Annotation

• Atlas domain: Support Tooling And Documentation / tools.
• Implementation status: atlas-only.

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.
