Now kmemcheck_pagealloc_alloc() is only called by __alloc_pages_slowpath(). __alloc_pages_nodemask() __alloc_pages_slowpath() kmemcheck_pagealloc_alloc() And the page will not be tracked by kmemcheck in the following path. __alloc_pages_nodemask() get_page_from_freelist() So move kmemcheck_pagealloc_alloc() into __alloc_pages_nodemask(), like this: __alloc_pages_nodemask() ... get_page_from_freelist() if (!page) __alloc_pages_slowpath() kmemcheck_pagealloc_alloc() ...
