Firstly, it has:\n\n  rmem < READ_ONCE(sk->sk_rcvbuf)\n\nto check if the just increased rmem value fits into the socket's receive\nbuffer. If not, it proceeds and tries to wait for the memory under:\n\n  rmem + skb->truesize > READ_ONCE(sk->sk_rcvbuf)\n\nThe checks don't cover the case when skb->truesize + sk->sk_rmem_alloc is\nequal to sk->sk_rcvbuf. Thus the function neither successfully accepts\nthese conditions, nor manages to reschedule the task - and is called in\nretry loop for indefinite time which is caught as:\n\n  rcu: INFO: rcu_sched
