Subject: [PATCH] xfs: xfs_fsops: drop useless LIST_HEAD
Git-commit: 90be9b86da9039fe6cf2880dc16fd0b0899603a5
Patch-mainline: v5.0-rc1
References: bsc#1191500, git-fixes

Drop LIST_HEAD where the variable it declares is never used.

Commit 0410c3bb2b88 ("xfs: factor ag btree root block
initialisation") stopped using buffer_list and started using a
buffer list in an aghdr_init_data structure, but the declaration
of buffer_list was not removed.

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

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

Fixes: 0410c3bb2b88 ("xfs: factor ag btree root block initialisation")
