Hi,
Any chance on this? As it gives a possible freeze on all Xen machines
that use rate-limiting, I really think we should backport this straight
forward patch.
Thanks

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
