Hi,

This series does some cleanups to reuse code, rename functions and simplify
logic to make code more clear. No functional changes are expected.

Changes from v2:
 - Add reviewed tag from Ryan. Thanks.
 - Pass vma instead of mm to shmem_huge_global_enabled(), per Ryan.

Changes from v1:
 - Add a dummy function in case CONFIG_TRANSPARENT_HUGEPAGE is not
 enabled, which fixes a building error reported by kernel test robot.

Baolin Wang (3):
  mm: shmem: simplify the suitable huge orders validation for tmpfs
  mm: shmem: rename shmem_is_huge() to shmem_huge_global_enabled()
  mm: shmem: move shmem_huge_global_enabled() into
    shmem_allowable_huge_orders()
