First of all, any dentry getting here would have passed bfs_lookup(),
so it it passed ENAMETOOLONG check there, there's no need to
repeat it.  And we are not going to get dentries with zero name length -
that check ultimately comes from ext2 and it's as pointless here as it
used to be there.

Yes, you are absolutely right, of course -- I must have looked at ext3
(I think it was ext3, not ext2) code at the time I wrote this and
assumed that it was necessary.

Kind regards,
Tigran
