[PATCH 15/20] NFS: drop useless LIST_HEAD

Julia Lawall
2018-12-23T09:35:02Z

Drop LIST_HEAD where the variable it declares has never
been used.

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
identifier x;
@@
- LIST_HEAD(x);
... when != x
// </smpl>

Fixes: 0e20162ed1e9 ("NFSv4.1 Use MDS auth flavor for data server connection")
