Subject: [PATCH v3 02/59] netfs, fscache: Combine fscache with netfs
Date: Thu, 7 Dec 2023 21:21:09 +0000 [thread overview]
Message-ID: <20231207212206.1379128-3-dhowells@redhat.com> (raw)
In-Reply-To: <20231207212206.1379128-1-dhowells@redhat.com>
Now that the fscache code is moved to be colocated with the netfslib code
so that they combined into one module, do the combining.
