Right now, whenever we exit for an hcall, upon return, we fetch
some register values from the structure that carries the hcall
results and update the vcpu accordingly.
However, if the hypercall chooses instead to update the registers
itself by calling set_regs, then we end up clobbering those

I just hope we can do better than a module option in future.
Thanks,

Hello folks,
The RFC-v5 patch for tcm_vhost kernel code was sent out for review a bit
less than 24 hours ago, and thus far there has not been any additional
comments.. Thanks to everyone who has been participating in the various
threads over the past week and giving their feedback!

Hi, Jens Rusty
This version is rebased against linux-next which resolves the conflict with
Paolo Bonzini's 'virtio-blk: allow toggling host cache between writeback and
writethrough' patch.
Patch 1/3 and 2/3 applies on linus's master as well. Since Rusty will pick up
patch 3/3 so the changes to
This patch introduces bio-based IO path for virtio-blk.
Compared to request-based IO path, bio-based IO path uses driver
provided -make_request_fn() method to bypasses the IO scheduler. It
handles the bio to device directly without allocating a request in block
layer. This reduces the IO path in

These shouldn't be needed. The device will not be useful without KVM,
so the file shouldn't be compiled for non-KVM case at all.
