Date: Fri, 10 Jul 2020 06:48:51 -0400 From: "Michael S. Tsirkin" <mst@...hat.com> To: linux-kernel@...r.kernel.org Cc: stable@...r.kernel.org, Jason Wang <jasowang@...hat.com>, Paolo Bonzini <pbonzini@...hat.com>, Stefan Hajnoczi <stefanha@...hat.com>, virtualization@...ts.linux-foundation.org, kvm@...r.kernel.org, netdev@...r.kernel.org Subject: [PATCH] vhost/scsi: fix up req type endian-ness vhost/scsi doesn't handle type conversion correctly for request type when using virtio 1.0 and up for BE, or cross-endian platforms. Fix it up using vhost_32_to_cpu. Cc: stable@...r.kernel.org Signed-off-by: Michael S.
