From 025f50f3866486a5278afa91f0d3b6b780141050 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Tue, 15 Oct 2019 21:18:21 +0200 Subject: sched/rt, workqueue: Use PREEMPTION CONFIG_PREEMPTION is selected by CONFIG_PREEMPT and by CONFIG_PREEMPT_RT. Both PREEMPT and PREEMPT_RT require the same functionality which today depends on CONFIG_PREEMPT. Update the comment to use PREEMPTION because it is true for both preemption models.
