sockets: repair wakeup of accept(2) by shutdown(2)
That was lost in transition from one-for-all soshutdown() to protocol
specific methods. Only protocols that listen(2) were affected. This is
not a documented or specified feature, but some software relies on it. At
least the FreeSWITCH telephony software uses this behavior on
PF_INET/SOCK_STREAM.
