/**
 * nilfs_bmap_truncate - truncate a bmap to a specified key

 * greater than or equal to @key from @bmap.
 *
 * Return Value: On success, 0 is returned. On error, one of the following
 * negative error codes is returned.
 *
 * %-EIO - I/O error.
 *
 * %-ENOMEM - Insufficient amount of memory available.
