If a program attempts to punch a hole on an inline data file, we need
to convert it to a normal file first.
This was detected using ext4/032 using the adv configuration. Simple
reproducer:
mke2fs -Fq -t ext4 -O inline_data /dev/vdc
mount /vdc
echo "" > /vdc/testfile
xfs_io -c 'truncate 33554432' /vdc/testfile
xfs_io -c 'fpunch 0 1048576' /vdc/testfile
umount /vdc
e2fsck -fy /dev/vdc
