Subject: [PATCH fb v1 5/6] fb: cache: Introduce `clearExpiredCaches()`
Date: Tue, 9 May 2023 17:46:57 +0700 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>
When a cache is expired, it won't be deleted unless getCache() with the
corresponding key is invoked. Introduce a new function to scan for
expired caches and delete them.
