这家伙很懒，什么也没写！

把 fdb_tsl_iter 这个函数修改一下，加一条状态判断就行
```c
void fdb_tsl_iter_by_status(fdb_tsdb_t db, fdb_tsl_cb cb, fdb_tsl_status_t status, void *arg)
{
    struct tsdb_sec_info sector;
    uint32_t sec_addr, traversed_len = 0;
    struct fdb_tsl tsl;

if (!db_init_ok(db)) {
        FDB_INFO("Error: TSL (%s) isn't initialize OK.\n", db_name(db));
    }

if (cb == NULL) {
        return;
    }

sec_addr = db->oldest_addr;
    /* search all sectors */
    do {
        traversed_len += db_sec_size(db);
        if (read_sector_info(db, sec_addr, §or, false) != FDB_NO_ERR) {
            continue;
        }
        /* sector has TSL */
        if (sector.status == FDB_SECTOR_STORE_USING || sector.status == FDB_SECTOR_STORE_FULL) {
            if (sector.status == FDB_SECTOR_STORE_USING) {
                /* copy the current using sector status  */
                sector = db->cur_sec;
            }

tsl.addr.index = sector.addr + SECTOR_HDR_DATA_SIZE;

/* search all TSL */
            do {
                read_tsl(db, &tsl);
                /* iterator is interrupted when callback return true */
                if(tsl.status == status) //判断tsl状态
                {
					if (cb(&tsl, arg)) {
						return;
					}
                }
            } while ((tsl.addr.index = get_next_tsl_addr(§or, &tsl)) != FAILED_ADDR);
        }
    } while ((sec_addr = get_next_sector_addr(db, §or, traversed_len)) != FAILED_ADDR);
}
```
