It was never able to invalidate busy buffers, but now there is a warning when it tries to do so. I would submit a patch to remove the invalidate_buffers() call from PV_FLUSH, but since the -ac kernel still has block devices in buffer cache, there is the _possibility_ of a disconnect between user space and kernel space w.r.t. snapshot data (which is written from kernel space).
