* * * This series of VMCI linux upstreaming patches include latest udpate from VMware to address Greg's and all other's code review comments. Summary of changes: - Rebase our linux kernel tree from v3.5 to v3.7. - Fix all checkpatch warnings and errors. Fix some checkpatch with -strict errors. This addresses Greg's comment: On 15 Nov 2012

This series adds the multi-transports support to vsock, following this proposal: https://www.spinics.net/lists/netdev/msg575792.html With the multi-transports support, we can use VSOCK with nested VMs (using also different hypervisors) loading both guest->host and host->guest transports at the same time. Before this series, vmci-transport supported this behavior but only using VMware

Most of the patches are reviewed by Dexuan, Stefan, and Jorgen. The following patches need reviews: - [11/15] vsock: add multi-transports support - [12/15] vsock/vmci: register vmci_transport only when VMCI guest/host are active - [15/15] vhost/vsock: refuse CID assigned to the guest->host transport RFC: https://patchwork.ozlabs.org/cover/1168442/ v1:
