[CRIU] stray unix socket not dumped by the diag module?

[Tycho Andersen]

Hi guys,

I'm getting a,

(00.155898) Error (sk-unix.c:294): sk unix: Unix socket 0x5674 not found

very rarely when dumping containers. This looks to be some kind of
unix socket that systemd has open, full log here:

http://paste.ubuntu.com/19219914/

but somehow, this socket didn't get dumped in collect_sockets(). I
looked through the kernel code, but it's not obvious to me why a
socket would be missing. Any ideas where to start digging?
