Both functions are updated so that the parameter type becomes wider, so all callers should be OK with it. Look at blk_do_pdiscard(): bytes is passed only to blk_check_byte_request() and bdrv_co_pdiscard(), which already have int64_t bytes parameter, so we are OK. Note that requests exceeding INT_MAX are still restricted by blk_check_byte_request().
