[CRIU] PID mismatch problem

[Federico Reghenzani]

I've attached the criu log for dump and restore when it fails for PID.
Today I noticed that the tty problem happens only if I tried to restore
manually via ssh (so it's not really a problem for us).

@Pavel how can I add --restore-sibling and -f via C API?



Cheers,
