Catalin Marinas 94f4a1618b mm: kmemleak: treat vm_struct as alternative reference to vmalloc'ed objects ... Kmemleak requires that vmalloc'ed objects have a minimum reference count of 2: one in the corresponding vm_struct object and the other owned by the vmalloc() caller. There are cases, however, where the original vmalloc() returned pointer is lost and, instead, a pointer to vm_struct is stored (see free_thread_stack()). Kmemleak currently reports such objects as leaks. This patch adds support for treating any surplus references to an object as additional references to a specified object. It introduces the kmemleak_vmalloc() API function which takes a vm_struct pointer and sets its surplus reference passing to the actual vmalloc() returned pointer. The __vmalloc_node_range() calling site has been modified accordingly.
