Thanks Fengguang:

For the record, I was able to find my own easy repro, last night using
only a 220 meg partition:

# mke2fs -t ext4 -b 1024 -J size=1 /dev/vdc
# mount -t ext2 /dev/vdc /vdc
# mkdir /vdc/a
# cd /vdc/a
# seq 1 210000  | xargs -n 1 fallocate -l 1m
# seq 1 2 210000  | xargs /bin/rm
# mkdir /vdc/b
# cd /vdc/b
# seq 1 103 | xargs -n 1 fallocate -l 1g
# cd /
# umount /vdc
# mount -t ext4 -o commit=10000 /dev/vdc /vdc
# rm -rf /vdc/b

Can you submit this for xfstests?
