+//! IRQ abstractions.
+//!
+//! An IRQ is an interrupt request from a device. It is used to get the CPU's
+//! attention so it can service a hardware event in a timely manner.
+//!
+//! The current abstractions handle IRQ requests and handlers, i.e.: it allows
+//! drivers to register a handler for a given IRQ line.
+//!
+//! C header: [`include/linux/device.h`](srctree/include/linux/interrupt.h)
+
+/// Flags to be used when registering IRQ handlers.
+mod flags;
