^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) Description:	Directory containing information about the system's IRQs.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) 		Specifically, data from the associated struct irq_desc.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 		The information here is similar to that in /proc/interrupts
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 		but in a more machine-friendly format.  This directory contains
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 		one subdirectory for each Linux IRQ number.
