For each request that is sent to the FCP adapter, zfcp allocates memory. Status information and data that is being read from the device is written to this memory by the hardware. After that, the hardware signals this via the response queue and zfcp continues processing. Now, if zfcp detects that there is a signal for an incoming response from the hardware, but there is no outstanding request for that request id, then some memory that can be in use anywhere in the system has just been overwritten. This should never happen, but if it does, stop the system with a panic. Signed-off-by:
