From: xu xin <xu.xin16@zte.com.cn>

mm_slot.h is mainly used by THP and KSM.

Patch 1 introduces mm_slot_remove() to abstract the common
hash_del() + list_del() sequence used in both khugepaged and KSM.

Patch 2 adds a comment explaining why mm_slot_lookup/insert cannot
be converted to static inline functions.

xu xin (2):
  mm/mm_slot.h: add a helper function mm_slot_remove
  mm/mm_slot.h: add comments for mm_slot_lookup/insert
