Subject: [PATCH v11 19/26] dept: Apply timeout consideration to waitqueue wait
Date: Wed, 24 Jan 2024 20:59:30 +0900 [thread overview]
Message-ID: <20240124115938.80132-20-byungchul@sk.com> (raw)
In-Reply-To: <20240124115938.80132-1-byungchul@sk.com>
Now that CONFIG_DEPT_AGGRESSIVE_TIMEOUT_WAIT was introduced, apply the
consideration to waitqueue wait, assuming an input 'ret' in
___wait_event() macro is used as a timeout value.
