From 786c96e92fb9e854cb8b0cb7399bb2fb28e15c4b Mon Sep 17 00:00:00 2001 From: Jinjie Ruan Date: Thu, 24 Aug 2023 14:43:36 +0800 Subject: net: arcnet: Do not call kfree_skb() under local_irq_disable() It is not allowed to call kfree_skb() from hardware interrupt context or with hardware interrupts being disabled. So replace kfree_skb() with dev_kfree_skb_irq() under local_irq_disable(). Compile tested only.
