reovim-kernel 0.14.3

//! Stable Kernel API v1.
//!
//! Linux equivalent: `include/linux/`
//!
//! This module provides the stable public interface for drivers and modules.
//! All types exported here are covered by semver guarantees within the v1.x series.
//!
//! # Stability Guarantee
//!
//! - Breaking changes require a new major version (v2)
//! - New APIs may be added in minor versions
//! - Patch versions contain only bug fixes
//!
//! # Usage
//!
//! ```ignore
//! use reovim_kernel::api::v1::*;
//!
//! // Check API compatibility
//! check_api_version(Version::new(1, 0, 0))?;
//!
//! // Use kernel types
//! let bus = EventBus::new();
//! pr_info!("kernel initialized");
//! ```
