Shinx emits a warning due to an extra function parameter in the current function docstring for simple_write_end(). While we are fixing this warning we might as well clean up the whole function docstring for this function. The current member descriptions are readable in text and also ok in HTML. When vfs.txt is converted to use RST format these member descriptions could be improved with a reference to struct address_space_operations docs in that file.
