+          to SMB/CIFS EAs. EAs are stored on Windows servers without the
+          user namespace prefix, but their names are seen by Linux cifs clients
+          prefaced by the user namespace prefix. The system namespace
+          (used by some filesystems to store ACLs) is not supported at
+          this time.

fs/cifs/CHANGES

+Version 1.22
+------------
+Add config option to enable XATTR (extended attribute) support, mapping
+xattr names in the "user." namespace space to SMB/CIFS EAs.
+
+Version 1.21
+------------
+Add new mount parm to control whether mode check (vfs_permission) is done on
+the client.  If Unix extensions are enabled and the uids on the client
+and server do not match, client permission checks are meaningless on
+server uids that do not exist on the client (this does not affect the
+normal ACL check which occurs on the server).  Fix default uid
+on mknod to match create and mkdir. Add optional mount parm to allow
+override of the default uid behavior (in which the server sets the uid
+and gid of newly created files). Normally for network filesystem mounts
+user want the server to set the uid/gid on newly created files (rather than 
+using uid of the client processes you would in a local filesystem).
+
 Version 1.20
 ------------
 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps

 		mount helper will not prompt the user for a password

+		Note that this is in addition to the normal ACL check on the

+		Client permission checking is enabled by default.
+  noperm        Client does not do permission checks.  This can expose
+		files on this mount to access by other users on the local
+		client system. It is typically only needed when the server
+		supports the CIFS Unix Extensions but the UIDs/GIDs on the
+		client and server system do not match closely enough to allow
+		access by the user doing the mount.

+		ACL against the user name provided at mount time).
+  setuids       If the CIFS Unix extensions are negotiated with the server
+		the client will attempt to set the effective uid and gid of
+		the local process on newly created files, directories, and
+		devices (create, mkdir, mknod).
+  nosetuids     The client will not attempt to set the uid and gid on
+		on newly created files, directories, and devices (create, 
+		mkdir, mknod) which will result in the server setting the
+		uid and gid to the default (usually the server uid of the
