[PATCH 08/20] xfs: xfs_buf: drop useless LIST_HEAD
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/) // @@ identifier x; @@ - LIST_HEAD(x); ... when != x // Fixes: 26f1fe858f274 ("xfs: reduce lock hold times in buffer writeback") Signed-off-by: Julia Lawall --- Successfully 0-day tested on 151 configurations. fs/xfs/xfs_buf.c |1 - 1 file changed, 1 deletion(-) diff --git a/fs/xfs/xfs_buf.c b/fs/xfs/xfs_buf.c index b21ea2ba768d..eedc5e0156ff 100644 --- a/fs/xfs/xfs_buf.c +++ b/fs/xfs/xfs_buf.c @@ -1992,7 +1992,6 @@ xfs_buf_delwri_submit_buffers( struct list_head*wait_list) { struct xfs_buf *bp, *n; - LIST_HEAD (submit_list); int pinned = 0; struct blk_plug plug;
