[PATCH] UBC: missed wakup on one ub refill path The following scenario is possible: - TCPSNDBUF rejected by ub_sock_get_wreserv - sys_poll -> ub_sock_snd_queue_add - uncharge -> sk->sk_write_space DOES NOT wakeup the waiting poll as the queue is too long After this, no one will wakeup the process :( And it will block till the poll timeout end. The patch makes sure, that the generic code will send wakeup when appropriate. Bug #89127
