--------------------------------

[ Upstream commit 313950c2 ]

It is not allowed to call kfree_skb() from hardware interrupt
context or with interrupts being disabled. All the SKBs have
been dequeued from the old queue, so it's safe to enqueue these
SKBs to a free queue, then free them after spin_unlock_irqrestore()
at once. Compile tested only.
