Maybe this is the sk_alloc problem I pointed out in my other mail?
Else you'll need some printks.

There are two issues here with sysctl.

the "unknown binary path" happens because the new sysctl check code
no longer allows you to do recursive sysctl registrations anymore.
You now need to do a lot of funky stuff involving path structs
and so on - I look at it briefly and haven't grokked it fully yet.
I'd ignore the issue for now and hard-code af_rds and sol_rds in your
test app, just so that you can go ahead with your testing.
