udf_setsize() can race with udf_writepages() as follows: udf_setsize() udf_writepages() if (iinfo->i_alloc_type == ICBTAG_FLAG_AD_IN_ICB) err = udf_expand_file_adinicb(inode); err = udf_extend_file(inode, newsize); udf_adinicb_writepages() memcpy_from_file_folio() - crash because inode size is too big. Fix the problem by checking the file type under folio lock in udf_handle_page_wb() handler called from __mpage_writepages() which properly serializes with udf_expand_file_adinicb().
