Subject: [PATCH] net: arcnet: Do not call kfree_skb() under local_irq_disable()
Date: Thu, 24 Aug 2023 14:43:36 +0800 [thread overview]
Message-ID: <20230824064336.1889106-1-ruanjinjie@huawei.com> (raw)
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.
Fixes: 05fcd31cc472 ("arcnet: add err_skb package for package status feedback")
