I tried the Joonsoo's CMA patches [1] in my part and found that they works better than mine [2] about handle LRU and other issues even if they don't shrink the memory before cma_alloc. So I began to test it in my part. But my colleague Weixing found some issues around it. So we make 2 patches to handle the issues. And I merged cma_alloc_counter from [2] to cma_alloc work better. This patchset is based on aa39477b5692611b91ac9455ae588738852b3f60 and [1].
