question on context of kfree_skb()

Hi,

I am getting reports about kfree_skb being called in hard IRQ. Which context should it be called in?

Regards

kfree_skb() should be called when you are not in hard irq context (i.e. in_irq() returns false). Same thing for dev_kfree_skb(), which is a #define for kfree_skb(). Not in hard irq context means you are either in softirq context (bottom half) or process context.

dev_kfree_skb_irq() should be called when you are in interrupt context.

dev_kfree_skb_any() should be called when you could be either executing in interrupt context or not.
