Hi Tom, I have stumbled over the following construct in xgbe_map_rx_buffer order = max_t(int, PAGE_ALLOC_COSTLY_ORDER - 1, 0); which looks quite suspicious. Why does it PAGE_ALLOC_COSTLY_ORDER - 1? And why do you depend on PAGE_ALLOC_COSTLY_ORDER at all? Thanks! -- Michal Hocko SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
