Subject: [PATCH 3/9] cifs: rename the *_shroot* functions to *_cached_dir*
Date: Tue, 9 Mar 2021 09:07:29 +1000 [thread overview]
Message-ID: <20210308230735.337-4-lsahlber@redhat.com> (raw)
In-Reply-To: <20210308230735.337-1-lsahlber@redhat.com>
These functions will eventually be used to cache any directory, not just the root
so change the names.
