Transparent hugepages are on by default. Disable it in kdump kernel by adding parameter transparent_hugepage=never. This might help us with some of the memory issues we are facing.

Hi Li Wang,
Could you also add the reason into patch log that transparent hugepage could eat too much memory and it doesn't matter the dumping in 2nd kernel?
And did you test this patch in x86 and other ARCHs? I think at least 2 ARCHs are needed.
Thanks Baoquan

Hi Baoquan,
No, I haven't do any test until now. Since I just saw that issue was point out by Vivek in bugzilla such a long time.
Okay, I will update the details, which include the reasons and test results. Perhaps a bit late, because I have some other things to queue in hands. :)
Best, Li Wang

No worry. It needn't be finished at once. Just before the end of rhel7.2.
As you know, our many commits has experienced several rounds of review and repost, like v7, v8. Your v3 should be OK, it has been so good. Good for you.
