On one of our servers, we find the dentry is continuously growing without shrinking. We're not sure whether that is because reclaimable slab is still less than min_slab_pages. So if we expose min_slab_pages, it would be easy to compare. As we can set min_slab_ratio with sysctl, we should expose the effective min_slab_pages to user as well. That is same with min_unmapped_pages.
