Hi Christian,

Thanks for your detailed report.

Now we have pinned down the bug, it's a bit overflow for multiplying
unsigned int.

At least not some fundamental design defeat of btrfs-convert.

The fix has been Cced to you, and passed my local test.
Test case has also been submitted.

Thanks again for your help!
Qu
