I don't think it even works correctly for ext*. *_dump_log() calls
dumpe2fs -h, which displays the superblock contents, not the journal
contents themselves, which is (I think) what this helper is supposed to
do.
It really ought to do something along the lines of:
echo 'logdump -a' | debugfs $SCRATCH_DEV
Though fixing this is probably something the ext4 developers should look
at...

Agreed. ;)
