I am seeing this as well since the 27th of February on our CentOS 7 box. Do you use sophos? We have sophos central and this appears to be related to it.

There are references to mtdd here: https://community.sophos.com/kb/en-us/124433#Configuration%20options%20to%20turn%20on%20mtdd%20debug%20or%20trace%20logging https://community.sophos.com/kb/en-us/128014
