From bb07fafaec70183f1dcd3d4a1459abbc409753e2 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 16 Nov 2016 05:49:22 -0800 Subject: [PATCH] net/mlx4_en: remove napi_hash_del() call There is no need calling napi_hash_del()+synchronize_rcu() before calling netif_napi_del() netif_napi_del() does this already. Using napi_hash_del() in a driver is useful only when dealing with a batch of NAPI structures, so that a single synchronize_rcu() can be used. mlx4_en_deactivate_cq() is deactivating a single NAPI.
