Hello, I am trying to apply CMA feature for my platform. My kernel version, 3.10.x, is not allocating memory from CMA area so that I applied a Joonsoo Kim's patch (https://lkml.org/lkml/2014/5/28/64). Now my platform can use CMA area effectively.
But I have many failures to allocate memory from CMA area. I found the same situation to Laura Abbott's patch descrbing, https://lkml.org/lkml/2012/8/31/313, that releases buffer-heads attached at CPU's LRU list. If Joonsoo's patch is applied and/or CMA feature is applied more and more, buffer-heads problem is going to be serious definitely. Please look into the Laura's patch again. I think it must be applied with Joonsoo's patch. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
