Subject: [PATCH v1 5/7] event/dlb2: avoid credit release race condition
Date: Thu, 8 May 2025 23:23:59 -0500 [thread overview]
Message-ID: <20250509042401.2634765-6-pravin.pathak@intel.com> (raw)
In-Reply-To: <20250509042401.2634765-1-pravin.pathak@intel.com>
While unlinking ports, all associated credits should be released.
This commit avoids race condition when main thread is unlinking
while workers are running.
