Could you test above patches in your kernel?
You have to apply [2/4], [3/4], [4/4] and don't need [1/4].
AFAIR without patch [1/4], free cma page counter will go below zero
and weird thing will happen, so better apply the complete patchset.
I can't understand your point. [1/4] is just fix for correcting trace
No?
I just remember we ran into such strange negative number of free cma
pages issue without that patch, but maybe the final patchset will
simply fail to apply without the first patch.
I have no objection to apply them all, of course.
But note that if you suffer from such strange bug without [1/4],
it should be dug in without buring into just "fixing of the trace"
comment. As I saw the code without [1/4], I can't find any fault.
Could you elaborate it more if you have any guessing in mind?
