[CRIU] GSoC 2019 application

[Vaibhav Gupta]

I did run following commands:
$ cat /proc/sys/kernel/tainted
12289
$ ps -efly | grep 12289
S varodek  15568 15519  0  80   0  2248  1645 -      09:43 pts/1
00:00:00 grep --color=auto --exclude-dir=.bzr --exclude-dir=CVS
--exclude-dir=.git --exclude-dir=.hg --exclude-dir=.svn 12289

I guess tainting is caused by zdtm.py only. at line 1975 2306
