I overlooked the Fixes tag. Thanks for pointing that out. I will add: Fixes: e13a6915a03f ("vhost/vsock: add IOTLB API support") > Do we need to do the same in vhost-net too? Yes, vhost-net has the same IOTLB lifecycle issue. I previously posted a separate patch for vhost-net: https://lore.kernel.org/all/20260726141158.1652386-1-physicalmtea@gmail.com/ I will update that patch in the next version to use the common IOTLB teardown handling for the ACCESS_PLATFORM transition, while retaining the vhost-net-specific checks for IN_ORDER and other unsafe feature changes. Thanks, Jia
