Date: Thu Mar 18 2021 - 08:29:06 EST

Hi all,
This series contains cleanups to rework some function logics to make it
more readable, use helper function and so on. More details can be found
in the respective changelogs. Thanks!

use ALIGN/ALIGN_DOWN too against HPAGE_PMD_SIZE per Peter.

rename try_to_split_huge_pmd_address and move up comments.

Miaohe Lin (6):
mm/huge_memory.c: rework the function vma_adjust_trans_huge()
mm/huge_memory.c: make get_huge_zero_page() return bool
mm/huge_memory.c: rework the function do_huge_pmd_numa_page() slightly
mm/huge_memory.c: remove redundant PageCompound() check
mm/huge_memory.c: remove unused macro
mm/huge_memory.c: use helper function migration_entry_to_page()
