Replenishment of receive buffers is done in the tasklet handling received frames as well as in a workqueue. When we are in the tasklet we cannot sleep and thus attempt atomic skb allocations. It is generally not a big problem if this fails since iwl_rx_allocate is always followed by a call to iwl_rx_queue_restock which will queue the work to replenish the buffers at a time when sleeping is allowed. We thus add the __GFP_NOWARN to the skb allocation in iwl_rx_allocate to reduce the noise if such an allocation fails while we still have enough buffers. We do maintain the warning and the error message when we are low on buffers to communicate to the user that there is a potential problem with memory availability on system This addresses issue reported upstream in thread "iwlagn: order 2 page allocation failures" in http://thread.gmane.org/gmane.linux.kernel.wireless.general/39187 Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Acked-by: Mel Gorman <mel@csn.ul.ie> Signed-off-by: John W.
