From f9ec8131bba25d4381c4c7f80dcf8532b864f652 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Sat, 15 Mar 2014 16:23:31 -0700 Subject: cxgb3: Call dev_kfree/consume_skb_any instead of [dev_]kfree_skb. Replace kfree_skb with dev_consume_skb_any in free_tx_desc, and write_tx_pkt_wr that can be called in hard irq and other contexts. Replace dev_kfree_skb with dev_kfree_skb_any in t3_eth_xmit that can be called in hard irq and other contexts. dev_kfree_skb is replaced with dev_kfree_skb_any in t3_eth_xmit as that location is a packet drop, while kfree_skb in free_tx_desc, and in write_tx_pkt_wr are places where packets are consumed in a healthy manner.
