The checks we do in udf_setsize() and udf_file_write_iter() are safe to do only with i_rwsem locked as it stabilizes both file type and file size. Hence we don't need to lock i_data_sem before we enter udf_expand_file_adinicb() which simplifies the locking somewhat. Signed-off-by: Jan Kara <jack@suse.cz>
