Hi ZhiJun DENG

In linux-4.7-rc1 the log says,
1,	206a81c18401 ("lzo: properly check for overruns") was reverted by
	af958a38a60c ("Revert "lzo: properly check for overruns"")

2, then it was fixed in 
	72cf90124e8 ("lzo: check for length overrun in variable length encoding.")

btw, please send email in pure text to LKML.
