Subject: Re: [PATCH 1/4] sched/cache: Keep nr_pref_llc_running in the runnable domain
Date: Wed, 16 Sep 2026 16:33:28 +0300	[thread overview]
Message-ID: <20260916133328.3422-1-kayracizmeci@gmail.com> (raw)
In-Reply-To: <20260916123046.GE776954@noisy.programming.kicks-ass.net>

> Needs a fixes tag.

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 :>
