Please change tests with following consideration as KMD behaves like that now,

1. These parameter can be set through sysfs, (and sysfs setting would always be done by super user) , normal permission cant change sysfs
2. Other way to set these parameters is through ioctls (like engine_create and passing parameter), here we will have differentiation for superuser and normal user as we used to do in tests till now.

So if you are writing tests for sysfs then please follow 1.

Thanks,
Tejas
