Subject[Patch v3 0/7] mm/hugetlb: code refine and simplification
Following are some cleanup for hugetlb.

Simple test with tools/testing/selftests/vm/map_hugetlb pass.

* rebase on v5.9-rc2 which adjust the last patch a little
* drop 5/6/10 since similar patches are merged or under review.
* adjust 2 based on comment from Mike Kravetz

Wei Yang (7):
mm/hugetlb: not necessary to coalesce regions recursively
mm/hugetlb: remove VM_BUG_ON(!nrg) in
mm/hugetlb: use list_splice to merge two list at once
mm/hugetlb: count file_region to be added when regions_needed != NULL
mm/hugetlb: a page from buddy is not on any list
mm/hugetlb: narrow the hugetlb_lock protection area during preparing
huge page
mm/hugetlb: take the free hpage during the iteration directly
