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.
Just to make sure I understood you correctly, you're saying Laura's
patch at <https://lkml.org/lkml/2012/8/31/313> fixes your issue?
Yes, it is.
