Hi Cole,
I merged crobinso/qcow2-data_file branch to 37b565c00. Reserved new

Could you please check this issue?
The full threads backtrace is in attachment
Thanks for checking. I'm struggling to see how that backtrace could be
related to this series, or even determine what the issue is. Can you
confirm that master branch doesn't have any issue? If it doesn't, can
you bisect the series to figure out where the offending patch is?
Thanks,
Cole
