--- Comment #8 from Theodore Tso (tytso@....edu) ---
e4defrag reports directories as failures.   We should probably change it to
just skip directories so it doesn't confuse people:

root@...-xfstests:~# mke2fs -Fq -t ext4 /dev/vdc
/dev/vdc contains a ext4 file system
        last mounted on Sat Sep 27 22:14:06 2025
root@...-xfstests:~# mount /dev/vdc /vdc
[  118.187747] EXT4-fs (vdc): mounted filesystem
c6ef56ee-8512-4408-8a58-2c83e3a36f91 r/w with ordered data mode. Quota mode:
none.
root@...-xfstests:~# e4defrag /vdc
e4defrag 1.47.2 (1-Jan-2025)
ext4 defragmentation for directory(/vdc)

        Success:                        [ 0/2 ]
        Failure:                        [ 2/2 ]
root@...-xfstests:~# find /vdc -type d
/vdc
/vdc/lost+found
root@...-xfstests:~# 

I am not seeing the "Failure to defrag with EXT4_IOC_MOVE_EXT ioctl" message
which you cited.   So I don't believe I'm able to reproduce whatever you're
seeing.
