Drop LIST_HEAD where the variable it declares is never used. Commit 31c02e215700 ("IPoIB: Avoid using stale last_send counter when reaping AHs") removed the uses, but not the declaration. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier x; @@ - LIST_HEAD(x); ... when != x // </smpl> Fixes: 31c02e215700 ("IPoIB: Avoid using stale last_send counter when reaping AHs") Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- Successfully 0-day tested on 151 configurations. drivers/infiniband/ulp/ipoib/ipoib_ib.c | 1 - 1 file changed, 1 deletion(-) diff --git a/drivers/infiniband/ulp/ipoib/ipoib_ib.c b/drivers/infiniband/ulp/ipoib/ipoib_ib.c index 6d35570092d6..78fa777c87b1 100644 --- a/drivers/infiniband/ulp/ipoib/ipoib_ib.c +++ b/drivers/infiniband/ulp/ipoib/ipoib_ib.c @@ -669,7 +669,6 @@ static void __ipoib_reap_ah(struct net_device *dev) { struct ipoib_dev_priv *priv = ipoib_priv(dev); struct ipoib_ah *ah, *tah; - LIST_HEAD(remove_list); unsigned long flags; netif_tx_lock_bh(dev);
