Subject: [PATCH v2 13/19] qcow2: Schedule cache-clean-timer in realtime
Date: Mon, 10 Nov 2025 16:48:48 +0100 [thread overview]
Message-ID: <20251110154854.151484-14-hreitz@redhat.com> (raw)
In-Reply-To: <20251110154854.151484-1-hreitz@redhat.com>
There is no reason why the cache cleaning timer should run in virtual
time, run it in realtime instead.
Suggested-by: Kevin Wolf <kwolf@redhat.com>
Signed-off-by: Hanna Czenczek <hreitz@redhat.com>
