Subject: [PATCH 3/6] iomap: treat a write through cache the same as FUA
Date: Wed, 19 Jul 2023 13:54:14 -0600 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>
Whether we have a write back cache and are using FUA or don't have
a write back cache at all is the same situation. Treat them the same.
