Muchun Song 8f0b364973 mm: kfence: fix objcgs vector allocation ... If the kfence object is allocated to be used for objects vector, then this slot of the pool eventually being occupied permanently since the vector is never freed. The solutions could be (1) freeing vector when the kfence object is freed or (2) allocating all vectors statically. Since the memory consumption of object vectors is low, it is better to chose (2) to fix the issue and it is also can reduce overhead of vectors allocating in the future.
