Linux Virtualization - Mar 2010 - [PATCH 0/7] virtio: console: Fixes, new flexible way of discovering ports

Hello all,

This new patchset switches over to using the control queue for port
discovery so that we can stay in sync with the host for port
enumeration and also don't use bitmaps to limit us to config space
sizes.

This changes the ABI, so it would be better to merge this for 2.6.34
so that we don't have to worry about released kernels with the older
ABI.

This looks horribly like development during the merge window.

Sorry,
