Some words on why this change is needed would be good.

Hmm, if I run this find command manually, I got warning about -maxdepth
position.

# find `pwd` -inum 3932421 -maxdepth 1
find: warning: you have specified the -maxdepth option after a non-option argument -inum, but options are not positional (-maxdepth affects tests specified before it as well as those specified after it).  Please specify options before other arguments.

/root/xfstests/check

Move -maxdepth option just after find path works fine

# find `pwd` -maxdepth 1 -inum 3932421 
/root/xfstests/check

But I'm not sure why I didn't see this warning by running overlay/017..
Anyway, moving -maxdepth around seems better to me.

Thanks,
Eryu
