202 2.4.1 KF_ACQUIRE flag
205 The KF_ACQUIRE flag is used to indicate that the kfunc returns a pointer to a
218 another helper). This flag is often used in pairing with KF_ACQUIRE flag, but
242 2. Pointers which were returned from a KF_ACQUIRE kfunc.
317 consider doing refcnt != 0 check, especially when returning a KF_ACQUIRE
318 pointer. Note as well that a KF_ACQUIRE kfunc that is KF_RCU should very likely
