Here is another thought.
In patch 5 you suggest removing all pages from hugetlb with the lock
held, and adding them to a list.  Then, drop the lock and free all
pages on the list.  If we do this, then the value computed here (min_count)
can not change while we are looping.  So, this patch would be unnecessary.
That is another argument in favor of batching the frees.

Unless there is something wrong in my thinking, I am going to take that
approach and drop this patch.

Makes sense
