Problem summary


    

  • Problem can happen only when DR operation is going on
constantly, and machine is under heavy load.
We won't see this problem if DR (e.g. cpu add/remove) is not
running even under heavy work load.

    



Problem conclusion


    

  • For 4K size memory, we don't unpin the the memory in net_free.
We will do this in netkmem_dr_cpu_remove when the cpu is
acutally being removed.
