[PATCH 0/3] mm: Rework {enabled,defrag}_{show,store}

[Gavin Shan <gshan@xxxxxxxxxx>]

The inappropriate settings can be accepted by "enabled" and "defrag"
interface, as the following example shows. This series reworks the
related functions and fixes the issue by the way.

   # cat /sys/kernel/mm/transparent_hugepage/enabled
     always [madvise] never
   # echo neveroff > /sys/kernel/mm/transparent_hugepage/enabled
   # cat /sys/kernel/mm/transparent_hugepage/enabled
     always madvise [never]

Gavin Shan (3):
  mm: Rework {enabled,defrag}_store()
  mm: Rework {enabled,defrag}_show()
  mm: Rework setup_transparent_hugepage()
