Hi Peter and Tim, The Fixes tag should be something like: Fixes: 714059f79ff0 ("sched/cache: Handle moving single tasks to/from their preferred LLC") This is the commit that adds this: env->src_rq->nr_pref_llc_running == env->src_rq->cfs.h_nr_runnable thing. It causes the issue so, you can use this, Tim. Hope this wasn't a unnecessary message. I wanted to say this since I already found the commit and didn't want you guys to search for it again. Thanks, Kayra :>
