Subject: Backport - xen-netback: correctly schedule rate-limited queues
Date: Tue, 11 Jul 2017 11:47:12 +0200 [thread overview]
Message-ID: <a8b4e68ed09513baa788427a0abd11f1@dupond.be> (raw)
Hi All,
Is there a chance the following patch
(https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/?id=dfa523ae9f2542bee4cddaea37b3be3e157f6e6b)
can get backported to the current LTS kernels (including 4.9.x)?
The commit message might not be completely showing the impact of this
issue (which is fixed with the patch).
Without the patch, ksoftirqd goes nuts if you upload on a domU with
rate-limiting enabled.
This not only causing high cpu load, but sometimes also a complete hang
of the hypervisor.
As the patch is quite important and trivial, I think it would be good to
have it backported :)
Thanks
Jean-Louis
