@@corey.bryant I've checked Pike and it has the fix included already, so
I'm attaching a debdiff for Ocata only.
@hopem About Trusty-Mitaka, it seems that it automatically pulled the
patch from Xenial's release so it looks good too.
** Patch added: "lp1818880-ocata.debdiff"
@corey.bryant I just spoke to @halves and he said that the series
targets above Bionic are an oversight since this patch landed in
anything newer than 2.11 (i.e. bionic version). We do also need this for
Trusty-Mitaka though so I have added that as a UCA target. I'll let
@halves reply about O/P.
Heiter, please if fixes are needed for ocata or pike can you provide us
with patches? We need to be careful not to skip cloud archive releases
(ie. if this is fixed in xenial but not the ocata and pike cloud
archive).

I've just accepted qemu version 1:2.11+dfsg-1ubuntu7.12~cloud0 into
queens-proposed however the changelog doesn't mention (LP: #1818880)
anywhere. Seeing that bionic is marked as fix released I assume queens
can be marked as fix released.

Fixed by upstream patch:
- d/p/lp-1818880-rcu-disable-atfork.patch: rcu: completely
Hi,
As this bug is very hard to trigger, I've been running some tests with qemu
1:2.5+dfsg-5ubuntu10.35 to see if we didn't regress or break anything with the
new patch. My test setup is as follows:
1) Create new QEMU guest with uvt-kvm or virt-install
# uvt-kvm create xenial release=xenial

Ok, for such complicated-to-reproduce issues I can understand it might
be hard to actually perform verification. In this case besides running
the listed test case (which might or might not actually trigger the
problem), could you also do some additional smoketesting/dogfooding of
the package once
