[CIFS] Use fsuid (fsgid) more consistently instead of uid/gid in

assembling smb requests when setuids and Linux protocol extensions enabled
and in checking more matching sessions in multiuser mount mode.

+Version 1.40
+------------
+Use fsuid (fsgid) more consistently instead of uid (gid).
+
 Version 1.39
 ------------
 Defer close of a file handle slightly if pending writes depend on that handle
@@ -7,6 +11,8 @@ Fix SFU style symlinks and mknod needed for servers which do not support the
 CIFS Unix Extensions.  Fix setfacl/getfacl on bigendian. Timeout negative
 dentries so files that the client sees as deleted but that later get created
 on the server will be recognized.  Add client side permission check on setattr.
+Timeout stuck requests better (where server has never responded or sent corrupt
+responses)
 
 Version 1.38
