A bit late but first we need a better and more generic API for ring/memory/region registration (see Patch 4), and it changes the API extending registered waits to be a generic parameter passing mechanism. That will be useful not only for waiting but also request arguments (msghdr, iovec, etc), upcomig rw with meta attrobitutes (PI), and for BPF proposal as well. I covered region registration with tests, but for reg waits it only enables the basic test. Need to enable and run the rest of them before merged.
