[PATCH] mm: fix oom roll-back of __vmalloc_area_node
__vunmap must not rely on area->nr_pages when picking the release methode for area->pages. It may be too small when __vmalloc_area_node failed early due to lacking memory. Instead, use a flag in vmstruct to differentiate. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
