Patch series "add common struct mm_slot and use it in THP and KSM", v2.
At present, both THP and KSM module have similar structures mm_slot for
organizing and recording the information required for scanning mm, and
each defines the following exactly the same operation functions:
- alloc_mm_slot
- free_mm_slot
- get_mm_slot
- insert_to_mm_slots_hash
In order to de-duplicate these codes, this patchset introduces a common
struct mm_slot, and lets THP and KSM to use it.
