So simple_write_end() is actually correct in that place. We cannot even
use generic_write_end() because that page doesn't have buffers attached -
it's a special case of a file which is smaller than a block and is packed
in the inode. Please test the patch better next time - this would oops on
you the first time you try to write to such a file. Thanks!
