From: "zhang.kai" <[email protected]> Problem: With each iteration of the vector_foreach_slot() loop statement, some slots couldn't be traversed when a slot is deleted from vector.
Reasons: Currently,loop's index 'i' is not decremented correspondingly when a slot is deleted from vector.Meanwhile, in the vector_foreach_slot() loop, mpp is assigned from vector newmp directly, so find_slot() could be omitted.
