It seems like Cisco and NVM should work together produce a solution. You could run into this issue even with entirely in tree modules. For example, we may have a v6.6 kernel but we need some modules from v5.15 for some incompatibility reason in v6.6. Then we may build the v5.15 modules as out of tree modules against the v6.6 kernel. You also have just normal developers making kernel modules which always start as out of tree modules before they are upstreamed. Those modules could be any level of complexity. I don't think it make sense to view this as strictly enhancing large of the tree modules with no upstream potential. Daniel
