Subject: Re: [PATCH] sched/deadline: Remove fair-servers from real-time task's bandwidth accounting

Hi,

Thank you very much for your testing, I'm very glad to know that the patch works
as intended.

At first glance, I think the warnings you are having are related to this bug
report that I posted a few days ago:
https://lore.kernel.org/all/20250718113848.193139-1-yurand2000@gmail.com/

Juri Lelli checked it out and made a patch that addresses these warns here:
https://lore.kernel.org/all/20250721-upstream-fix-dlserver-lessaggressive-b4-v1-1-4ebc10c87e40@redhat.com/

Have you already applied Juri's patch together with mine? If not, I think it
should solve those issues you mentioned.

Have a nice day,
Yuri
