Subject: Re: [dpdk-dev] [PATCH v11 0/5] net/virtio: support GUEST ANNOUNCE
Date: Thu, 18 Jan 2018 11:09:21 +0800 [thread overview]
Message-ID: <20180118030921.GW29540@yliu-mob> (raw)
In-Reply-To: <20180116214103.67803-1-xiao.w.wang@intel.com>
Xiao told me that this series (except the last patch) was already applied
to the Thomas master branch. I then realised it was my mistake.
I applied v10 last week locally for some basic testing. There is a conflict
in last patch, that's why the last patch is not merged. I forgot to do
a reset before I applied another patch. Then later, I did a push to the
next-virtio tree, thus patches from Xiao were also pushed. Ferruh then
did a pull from it. As a result, they got merged to the master branch
before I realised. Non-rebase is allowed there, thus I have made a patch
to fix my mistake.
Meanwhile, I have also spotted a build error when shared lib is enabled.
I will send them out soon.
