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@xxxxxxxxx/

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
