This patchset is based on the series of "Free some vmemmap pages of HugeTLB page". More details can refer to the below link. https://lkml.kernel.org/r/20210308102807.59745-1-songmuchun@xxxxxxxxxxxxx I often received some feedback (We want to test this feature on arm64) before. Because the previous code has been reviewed for 18 versions and is merged into mm tree, I think that it is time to release this patchset. If you want to test then you can start now :-). And I also hope someone can review this. Thanks.
