That's nearly a GB smaller.
That, too; I missed the DUP. Not quite as pronounced as in my

The patch below has one problem. The functions open_file_or_dir() in btrfsctl.c

Hi Itaru,
Thanks for testing, you seems to be using an old version, since in the new
version
record_extent_backrefs() does not own a WARN_ON().
Could you please test it
