<div dir="ltr">Well, I'm not sure. But after further analyse, I think that crypto creates some data on boot which are destroyed only when device is powering off, so it may be false positive.<br><div class="gmail_extra">

> I noticed that in 6 of 10 entries there are dm_ctl_ioctl, table_load and dm_table_add_target functions. So I think something is wrong with MD driver but I compared source of this driver with other find on net and there aren't any differences.<br>
