From: Naoya Horiguchi <n-horiguchi@xxxxxxxxxxxxx>
Subject: mm-memory-failurec-define-page-types-for-action_result-in-one-place-v3
ChangeLog v2 -> v3:
- rename action_page_type to action_page_types
- rename enum page_type to enum action_page_type
ChangeLog v1 -> v2:
- fix DIRTY_UNEVICTABLE_LRU typo
- adding "MSG_" prefix to each enum value
- use declaration with type "enum page_type" instead of int
- define action_type_type as "static const char * const" (not "static const=
char *")
