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/) // @@ identifier x; @@ - LIST_HEAD(x); ... when != x // Fixes: 0410c3bb2b88 ("xfs: factor ag btree root block initialisation") Signed-off-by: Julia Lawall Reviewed-by: Darrick J.
