Bug Description

Hi, Please include the following patch as it is required to do core dump on multiple vCPUs:

http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/patch/drivers/hv/connection.c?id=e28bab4828354583bb66ac09021ca69b341a7db4

Also please verify if the patch below is already integrated:
http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/patch/drivers/hv/connection.c?id=269f979467cf49f2ea8132316c1f00f8c9678f7c

I had already filed a bug for these patches before and the issue was resolved as fix released. However it appears that we missed the first patch entirely. Please accept.

Thanks,
Abhishek

May I suggest to move priority to high pri as without these patches we cannot core dump on multiple vCPUs. This is a significant customer pain point.
Thanks,
