From: Sven Eckelmann <sven.eckelmann@xxxxxx> A new buffer for a packet is created when a icmp packet is received. This happens in a context with disabled irq. Thus we are not allowed to sleep or call function which might sleep. kmalloc must be called with GFP_ATOMIC instead of GFP_KERNEL to ensure that it does not sleep.
