shmem_file_write is redundant
With the old aops, writing to a tmpfs file had to use its own special method: the generic method would pass in a fresh page to prepare_write when the right page was there in swapcache - which was inefficient to handle, even once we'd concocted the code to handle it. With the new aops, the generic method uses shmem_write_end, which lets shmem_getpage find the right page: so now abandon shmem_file_write in favour of the generic method. Yes, that does do several things that tmpfs hasn't really needed (notably balance_dirty_pages_ratelimited, which ramfs also calls); but more use of common code is preferable.
