staging: remove smbfs

smbfs got moved to staging in 2.6.37, so we can
finally remove it in the 2.6.39 merge window.
All users should by now have migrated to cifs.

-config SMB_FS
-	tristate "SMB file system support (OBSOLETE, please use CIFS)"
-	depends on BKL # probably unfixable
-	depends on INET
-	select NLS
-	help
-	  SMB (Server Message Block) is the protocol Windows for Workgroups
-	  (WfW), Windows 95/98, Windows NT and OS/2 Lan Manager use to share
-	  files and printers over local networks.  Saying Y here allows you to
-	  mount their file systems (often called "shares" in this context) and
-	  access them just like any other Unix directory.  Currently, this
-	  works only if the Windows machines use TCP/IP as the underlying
-	  transport protocol, and not NetBEUI.  For details, read
-	  <file:Documentation/filesystems/smbfs.txt> and the SMB-HOWTO,
-	  available from <http://www.tldp.org/docs.html#howto>.
-
-	  Note: if you just want your box to act as an SMB *server* and make
-	  files and printing services available to Windows clients (which need
-	  to have a TCP/IP stack), you don't need to say Y here; you can use
-	  the program SAMBA (available from <ftp://ftp.samba.org/pub/samba/>)
-	  for that.
-
-	  General information about how to connect Linux, Windows machines and
-	  Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.
-
-	  To compile the SMB support as a module, choose M here:
-	  the module will be called smbfs.  Most people say N, however.
-
-config SMB_NLS_DEFAULT
-	bool "Use a default NLS"
-	depends on SMB_FS
-	help
-	  Enabling this will make smbfs use nls translations by default. You
-	  need to specify the local charset (CONFIG_NLS_DEFAULT) in the nls
-	  settings and you need to give the default nls for the SMB server as
-	  CONFIG_SMB_NLS_REMOTE.
-
-	  The nls settings can be changed at mount time, if your smbmount
-	  supports that, using the codepage and iocharset parameters.
-
-	  smbmount from samba 2.2.0 or later supports this.
-
-config SMB_NLS_REMOTE
-	string "Default Remote NLS Option"
-	depends on SMB_NLS_DEFAULT
-	default "cp437"
-	help
-	  This setting allows you to specify a default value for which
-	  codepage the server uses. If this field is left blank no
-	  translations will be done by default. The local codepage/charset
-	  default to CONFIG_NLS_DEFAULT.
-
-	  The nls settings can be changed at mount time, if your smbmount
-	  supports that, using the codepage and iocharset parameters.

drivers/staging/smbfs/TODO

-smbfs is on its way out of the kernel, it has been replaced
-by cifs several years ago.
-
-The smbfs code uses the big kernel lock which
-is getting deprecated.
-
-Users that find smbfs to work but not cifs should contact
-the CIFS developers on linux-cifs@vger.kernel.org.

-Smbfs is a filesystem that implements the SMB protocol, which is the
-protocol used by Windows for Workgroups, Windows 95 and Windows NT.
-Smbfs was inspired by Samba, the program written by Andrew Tridgell
-that turns any Unix host into a file server for DOS or Windows clients.
-
-Smbfs is a SMB client, but uses parts of samba for its operation. For
-more info on samba, including documentation, please go to
-http://www.samba.org/ and then on to your nearest mirror.
