From 80390ead2080071cbd6f427ff8deb94d10a4a50f Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 26 Nov 2025 05:31:28 +0100 Subject: [PATCH] sched/fair: Separate se->vlag from se->vprot There's no real space concerns here and keeping these fields in a union makes reading (and tracing) the scheduler code harder.
