From 7395a90db87bcb2f617d3c486657813122d3f151 Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Mon, 31 Jul 2023 16:14:47 +0900 Subject: [PATCH] Add WAIT_EVENT_{CLASS,ID}_MASK in wait_event.c These are useful to extract the class ID and the event ID associated to a single uint32 wait_event_info. Only two code paths use them now, but an upcoming patch will extend their use.
