Subject: [PATCH v2 18/40] afs: Rename some fields
Date: Wed, 13 Dec 2023 13:49:40 +0000 [thread overview]
Message-ID: <20231213135003.367397-19-dhowells@redhat.com> (raw)
In-Reply-To: <20231213135003.367397-1-dhowells@redhat.com>
Rename the ->index and ->untried fields of the afs_vl_cursor and
afs_operation struct to ->server_index and ->untried_servers to avoid
confusion with address iteration fields when those get folded in.
