Annotated Snippet
清除 WARN_ONCE
--------------
WARN_ONCE / WARN_ON_ONCE / printk_once 仅仅打印一次消息.
echo 1 > /sys/kernel/debug/clear_warn_once
可以清除这种状态并且再次允许打印一次告警信息，这对于运行测试集后重现问题
很有用。Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- 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.
