Works for me.Maybe samba configuration issue. You need to have a writeable user
.
The below tells that issue is not with cifs driver.

root@junk-foo:/mnt/3# touch foo
root@junk-foo:/mnt/3# ls -l foo
-rw-r--r--+ 1 root root 0 Jun  1 10:20 foo
root@junk-foo:/mnt/3# mknod foo b 4 3
mknod: foo: File exists
root@junk-foo:/mnt/3# mknod devfoo b 4 3
root@junk-foo:/mnt/3# mkfifo pipe
root@junk-foo:/mnt/3# ls -l
total 0
brw-r--r-- 1 root root 4, 3 Jun  1 10:21 devfoo
-rw-r--r-- 1 root root    0 Jun  1 10:20 foo
