Name:Object colors, encoded with count and min_count:* - white - orphan object, not enough references to it (count < min_count)* - gray - not orphan, not marked as false positive (min_count == 0) or* sufficient references to it (count >= min_count)

Type:bool

Parameter:

TypeParameterName
const struct kmemleak_object *object
308  Return he total number of pointers found pointing to this object != KMEMLEAK_BLACK && he total number of pointers found pointing to this object < minimum number of a pointers found before it is considered leak
Caller
NameDescribe
