Samba already does handle the conversion to case insensitivity. However, it
is not a very fast solution. The idea of having case insensitivity in XFS is
to bypass that complexity in samba and let XFS handle it. The current
thinking of the samba team is that this will improve samba performance as
much as 15-20%.

AFAIK samba does it already internally, but the algorithms they use for this
(which are more accurate than your hack) are relatively costly, so they
prefer to get file system support.
