[linux-cifs-client] special files on Services for Unix (SFU) / Interix

Hello Steve,

this has nothing to do with special files on samba:
bash-2.05b$ ls -ln
total 2
drw-r--r--  1 3002  3003   6 Jun  3 23:56 hello_world
drw-rwxrw-  1 3002  3003   0 Jun  3 23:56 testblock
drw-rwxrw-  1 3002  3003   0 Jun  3 23:56 testchar
drw-rwxrw-  1 3002  3003   0 Jun  3 23:56 testfifo
drw-rwxrw-  1 3002  3003  30 Jun  3 23:56 testlink
bash-2.05b$ ls -ln *
-rw-r--r--  1 3002  3003         6 Jun  3 23:56 hello_world
brw-rwxrw-  1 3002  3003   44,  45 Jun  3 02:25 testblock
crw-rwxrw-  1 3002  3003   42,  43 Jun  3 02:25 testchar
prw-rwxrw-  1 3002  3003         0 Jun  3 02:25 testfifo
lrw-rwxrw-  1 3002  3003        11 Jun  3 02:25 testlink -> hello_world
bash-2.05b$

hello_world is a normal plain text file and is shown as
directory also. However, when doing "ls -ln *", all is ok.
I see this "directorisation" on all files and all shares
coming from my samba server, not only those with special files.
