cnic: Don't take rcu_read_lock in cnic_rcv_netevent() Because the called function, such as bnx2fc_indicate_netevent(), can sleep, we cannot take rcu_lock(). To prevent the rcu protected ulp_ops from going away, we use the cnic_lock mutex and set the ULP_F_CALL_PENDING flag. The code already waits for ULP_F_CALL_PENDING flag to clear in cnic_unregister_device(). Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
