[PATCH 1/2] mm/sparse: use page_private() to get page->private value

Show all headers | View raw

free_map_bootmem() uses page->private directly to set
removing_section_nr argument. But to get page->private
value, page_private() has been prepared.

So free_map_bootmem() should use page_private() instead of
page->private.
