Right, there are nommu users. Will anybody join LTP development to maintain
nommu support in LTP? The needed work is to add this support to LTP new C API
[1] and use it in the relevant test. There is some implementation in the old
API, I have no idea how well it worked.

If nobody stands for maintaing nommu, we will have to delete it. There is nobody
from the current maintainers who is using LTP on nommu HW (that is the reason why
nommu support have not been implemented in the new API).

Kind regards,
Petr
