From f9fc8cad9728124cefe8844fb53d1814c92c6bfc Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Tue, 6 Sep 2022 12:39:55 +0200 Subject: sched: Add TASK_ANY for wait_task_inactive() Now that wait_task_inactive()'s @match_state argument is a mask (like ttwu()) it is possible to replace the special !match_state case with an 'all-states' value such that any blocked state will match.
