When vmemmap pages allocation failed, the hugetlb pages fail to free,

You have misunderstand me and Mike. We mean the memory allocation
in vmemmap_remap_free() which also use __GFP_THISNODE, it has the
same issue as you fixed in another thread. But the failure of memory
allocation is not fetal. And it is better to remove __GFP_THISNODE
as well.
Thanks.
Ok, sorry about this, I will send another patch to remove __GFP_THISNODE in
vmemmap_remap_free, and I would like to know is it ok to add __GFP_NOWARN in
alloc_vmemmap_page_list()?
Do not do this. We need a warning here.
Thanks.
Ok, thanks for the reply.
