Ok, I think it's simple:
you've previously built criu on an older kernel with older uapi,
which has no struct tcp_repair_window.
Which means that you've criu/include/config.h generated
for the previous kernel.

Please, run `make mrproper` after updating kernel on dirty criu
directory before building new criu.
