I had this patch merged but still saw some problems. If there's eg. a
symlink to file on another filesystem, defrag fails with

"ERROR: defrag range ioctl not supported in this kernel, please try
without any options."

which does not match the error that occured.

In short, we have to use nftw and specify FTW_MOUNT (do not dive into
mountpoints) and FTW_PHYS (do not follow symlinks). Fixed and added to
integration. Please write the corresponding bits of manpage and send a
patch.

thanks,
david
