When I ran it on ext2, ext3 and ext4 which has dir_index feature disabled, I got something like this:
EXT3-fs error (device loop1): ext3_readdir: bad entry in directory #34817: rec_len is \
smaller than minimal - offset=993, inode=0, rec_len=0, name_len=0 EXT3-fs error \
(device loop1): ext3_readdir: bad entry in directory #34817: rec_len is smaller than \
minimal - offset=1009, inode=0, rec_len=0, name_len=0 EXT3-fs error (device loop1): \
ext3_readdir: bad entry in directory #34817: rec_len is smaller than minimal - \
offset=993, inode=0, rec_len=0, name_len=0 EXT3-fs error (device loop1): \
ext3_readdir: bad entry in directory #34817: rec_len is smaller than minimal - \
offset=1009, inode=0, rec_len=0, name_len=0
...
If we configured errors=remount-ro, the filesystem will become read-only.
And you can find more infomation in http://marc.info/?t=136123715300001&r=1&w=2 as i mentioned.
If this message is needed i'll add it in the patch v2.
Thanks
