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
