unix: Improve locking scheme in unix_show_fdinfo()
After switching to TCP_ESTABLISHED or TCP_LISTEN sk_state, alive SOCK_STREAM and SOCK_SEQPACKET sockets can't change it anymore (since commit 3ff8bff704f4 "unix: Fix race in SOCK_SEQPACKET's unix_dgram_sendmsg()"). Thus, we do not need to take lock here. Signed-off-by: Kirill Tkhai <tkhai@ya.ru> Reviewed-by: Kuniyuki Iwashima <kuniyu@amazon.com> Signed-off-by: David S. Miller <davem@davemloft.net>
