Creating a dm-verity device with mount then removing it and now if you create it

Each of the relevant dm ioctls should be logged separately each time. If that's
not happening it might need fixing.
Most likely this is because you haven't set CONFIG_IMA_DISABLE_HTABLE=y.
See "IMA: support for duplicate measurement records" [1] for details.
Please let us know if you still see this behavior after setting
CONFIG_IMA_DISABLE_HTABLE=y.
Thanks,
