Subject[PATCH 01/20] nfsd: drop useless LIST_HEAD
Date
Drop LIST_HEAD where the variable it declares is never used.

This was introduced in c5c707f96fc9a ("nfsd: implement pNFS
layout recalls"), but was not used even in that commit.

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

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

Fixes: c5c707f96fc9a ("nfsd: implement pNFS layout recalls")
Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr>
