From 6e6d305573458c640b97046667bb39a0d0e6bfa8 Mon Sep 17 00:00:00 2001 From: Mike Yuan Date: Tue, 30 Jul 2024 20:35:10 +0200 Subject: [PATCH] cgroup-setup: kernel threads can reside in arbitrary cgroups Realistically this doesn't matter, as cg_migrate() is only used to populate init.scope. But it's probably better to make things clear. --- src/shared/cgroup-setup.c | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/src/shared/cgroup-setup.c b/src/shared/cgroup-setup.c index 6292777369..cf7a0eb272 100644 --- a/src/shared/cgroup-setup.c +++ b/src/shared/cgroup-setup.c @@ -639,10 +639,7 @@ int cg_migrate( if (set_contains(s, PID_TO_PTR(pid))) continue; - /* Ignore kernel threads.
