  SVN rev 216626 on 2010-12-21 21:59:21Z by pjd
  
  Close body of the VFS_UNLOCK_GIANT() macro into do { } while (0) loop,
  so it can be used in code like this:
  
          if (cond)
                  VFS_UNLOCK_GIANT(vfslocked);
          else
                  ; /* Do something else. */
  
  Before the change, compiler couldn't decide on its own if else should be
  applied to the 'if (cond)' or to the if statement inside VFS_UNLOCK_GIANT()
  macro.
