[PATCH] relax nr_to_write requirements
Relax the requirements on the writeback_mapping a_op. This function is passed the number of pages which it should write. The current fs-writeback.c code will get confused if the address_space writes back more pages than it was asked to. With this change the address_space may write more pages than required if that is convenient. Extent-based fileystems may wish to do this.
