Subject: [PATCH v2 0/5] Cleanup and fixup for hugetlb

Hi all,
This series contains cleanups to remove redundant VM_BUG_ON() and
simplify the return code. Also this handles the error case in
hugetlb_fix_reserve_counts() correctly. More details can be found
in the respective changelogs. Thanks!

v1->v2:
  collect Reviewed-by tag
  remove the HPAGE_RESV_OWNER check per Mike
  add a comment to hugetlb_unreserve_pages per Mike
  expand warning message a bit for hugetlb_fix_reserve_counts
  Add a new patch to remove unused variable
  Many thanks for Mike's review and suggestion!
