I'd prefer we keep it so that the IOAS can be setup with an argument, this will greatly help syzkaller
Lets have it so a 0 ioas will avoid the setup so the second call can happen
I assume that you mean the iommufd_access_set_ioas() call and the "unsigned int ioas_id" input of iommufd_test_create_access?
Thanks Nic
