I audited the vhost ioctl code when reviewing this patch and was unable to find anything that would break for a 32-bit userspace process. drivers/vhost/net.c does the same thing already, which doesn't prove it's correct but makes me more confident I didn't miss something while auditing the vhost ioctl code. Did you have a specific ioctl in mind? Stefan
