holes there is Oops on mount after booting or shortly after writing to the file

1. Create a logical volume, format it with mkfs.xfs /dev/vg/lv
2. mount the filesystem and create a file with holes with xfs_mkfile -n 10G file
The size of the file is in my case 1GB below the size of the filesystem.

You should see Oops at mount or after a while when running stress-xfs, few power
failures maight be required.
