[CRIU] ./crtools check errors

[Qiang Huang]

Hi guys:

I rebuilt CRIU environment today and met some trouble in crtools check:

hq at ubuntu1210:~/crtools$ sudo ./crtools check
[sudo] password for hq:
(00.002312) Error (libnetlink.c:53): ERROR -2 reported by netlink
The sock diag infrastructure is incomplete.
Make sure you have:
 1. *_DIAG kernel config options turned on;
 2. *_diag.ko modules loaded (if compiled as modules).
(00.003262) Error (kerndat.c:91): Dirty tracking support is OFF


My kernel version is linux-cr v3.9-rc5, crtools' last commit is
bcd918b4ca19afb04f.

I did the kernel config exactly as installation guide(http://criu.org/Installation)
told, here is a check about _DIAG:

hq at ubuntu1210:~/linux-cr$ grep _DIAG .config
CONFIG_PACKET_DIAG=y
CONFIG_UNIX_DIAG=y
CONFIG_INET_DIAG=y
CONFIG_INET_TCP_DIAG=y
CONFIG_INET_UDP_DIAG=y
CONFIG_INET_DCCP_DIAG=m
# CONFIG_NETLINK_DIAG is not set

What did I miss? And thanks in advance~
