------------------ From: Sowmini Varadhan <[email protected]> Upstream commit 671d773297969bebb1732e1cdc1ec03aa53c6be2 Since it is possible for vnet_event_napi to end up doing vnet_control_pkt_engine -> ... -> vnet_send_attr -> vnet_port_alloc_tx_ring -> ldc_alloc_exp_dring -> kzalloc() (i.e., in softirq context), kzalloc() should be called with GFP_ATOMIC from ldc_alloc_exp_dring.
