Hello!

I made a fresh file to pretend being a disk with:

$ truncate -s 40M test

I then made it a block device and formatted it:

# losetup -f test
# mkfs.ext4 -L test -O verity /dev/loop1

When trying to enable fs-verity on a test file inside this new
fake-device I always get the error mentioned in the subject. Of course
I have CONFIG_FS_VERITY built-in to kernel, and the file I'm testing is
a regular file created with:

$ dd if=/dev/urandom bs=1K count=20 | base64 > a.txt

Any ideas, what's going on?

I will really appreciate help!

Thanks,
Wojciech Kuzyszyn
