Subject: Re: [PATCH 3/7] virt: steal_governor: remove the minimum elapsed-time check
Date: Fri, 13 Nov 2026 18:56:59 +0000 [thread overview]
Message-ID: <sashiko-outbox-213482@kernel.org> (raw)
In-Reply-To: <20261113184257.621707-4-ynorov@nvidia.com>
> The governor queues its worker with a sampling interval of at least
> 100ms, so its one-millisecond elapsed-time check is redundant. The
> existing denominator clamp already prevents division by zero when
> calculating the steal ratio.
>
> This series adds a hook on hotplug events. It may trigger this error
> path pointlessly. Just drop it.
