Look at this closer, are you sure you want? Why is page_reset_last_nid()
better or more consistent?
The getter functions for page-related fields start with page (page_count,
page_mapcount etc.) but the setters begin with set (set_page_section,
set_page_zone, set_page_links etc.). For mapcount, we also have
reset_page_mapcount() so to me reset_page_last_nid() is already
consistent.
