I'd think we'd want to flush the AIL then report the error, like this: if (gfs2_is_jdata(ip)) - filemap_write_and_wait(mapping); + ret = file_write_and_wait(file); gfs2_ail_flush(ip->i_gl, 1); + if (ret) + return ret; } -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
