Subject: [PATCH 5/6] lpfc: Introduce LOG_NODE_VERBOSE messaging flag
Date: Mon, 9 Oct 2023 09:18:11 -0700 [thread overview]
Message-ID: <20231009161812.97232-6-justintee8345@gmail.com> (raw)
In-Reply-To: <20231009161812.97232-1-justintee8345@gmail.com>
The preexisting LOG_NODE message flag frequently spams a subset of the same
log messages during normal FC driver operations. When analyzing driver
logs, this sometimes leads to difficulty in troubleshooting.
Because LOG_IP log message flag is unused, convert it to a new
LOG_NODE_VERBOSE flag. The LOG_NODE_VERBOSE shall specifically be used for
diagnosing issues that require precise ndlp tracking detail.
