Hmm... There isn't a get_nr_mapped_entries() in 2.6.30. Are these patches again the current linus tree?
For unfilled information I wanted to complain that for non-sg mapping sg_call_ents never gets filled. But as dma_entry_alloc() does a memset() to clean the entrys it should not matter. And what about dma_debug_entry.paddr? Should this also be compared?
