Its return value is completely ignored by its single caller and it's useless anyway, since errors are indicated through SetPageError and the bit AS_EIO set in the flags of the inode's mapping. The caller can't do anything with the value, as it's invoked from a workqueue task and not by the task calling filemap_fdatawrite_range (which calls the writepages address space callback, which in turn calls the inode's fill_delalloc callback).
