From bfef73fa78ca1e56175dcbd33aa11de4764f85a5 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Mon, 20 Mar 2006 10:08:26 -0800 Subject: [PATCH] IPoIB: Get rid of useless test of queue length In neigh_add_path(), the queue of delayed packets can never be full, because the queue is always freshly created and cannot be found by any other code path. In fact, the test of the queue length is worse than useless: if somehow the test ever triggered and path_rec_start() also failed, then dev_kfree_skb_any() will be called twice on the same skb. Fix this by deleting the useless test. Pointed out by Michael S. Tsirkin .
