WebSVN: http://websvn.samba.org/websvn/changeset.php?rep=samba&path=/branches/SAMBA_4_0/source&rev=3227&nolog=1 Log: added a per-share option "case insensitive filesystem", that tells the backend that the underlying filesystem is case insensitive, so it can bypass the directory search if the name is not found.
