Currently vhost-vsock doesn't have any feature bits, so it
don't support parse mergeable rx buffer feature. And the
feature is support in another series of patches named
"VSOCK: support mergeable rx buffer in vhost-vsock".
So we neet to support parse mergeable feature in vhost-vsock
if above patch
Hi everyone,
Currently, I found virtio-9p in VirtFS don't support "O_DIRECT + aio"
mode, both v9fs and qemu. So when user use "O_DIRECT + aio" mode and
increase iodepths, they can't get higher IOPS.
I want to know why v9fs don't implement this mode? And I will try to
implement this mode from now

Hi Eric and Greg,
I encountered the similar problem with create-unlink-getattr idiom.
I use the testcase that create-unlink-setattr idiom, and I see the
bug is reported at https://bugs.launchpad.net/qemu/+bug/1336794.
Then I also see you already fix the issue and push the patch to upstream.
