From 42ffda5fe704ab6a3ef8ca36b5f958a3cd86a164 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Sat, 15 Mar 2014 16:31:32 -0700 Subject: [PATCH] cxfb4vf: Call dev_kfree/consume_skb_any instead of [dev_]kfree_skb. Replace kfree_skb with dev_consume_skb_any in free_tx_desc that can be called in hard irq and other contexts. dev_consume_skb_any is used as this function consumes successfully transmitted skbs. Replace dev_kfree_skb with dev_kfree_skb_any in t4vf_eth_xmit that can be called in hard irq and other contexts, on paths that drop the skb. Replace dev_kfree_skb with dev_consume_skb_any in t4vf_eth_xmit that can be called in hard irq and other contexts, on paths that successfully transmit the skb. Signed-off-by: "Eric W.
