I'm sure that TINYRCU can be fixed if it really is the problem.
So I just want to make sure that we know what the root cause of your problem is. It's quite possible that it _is_ a real leak of filp or something, but before possibly wasting time trying to figure that out, let's see if your config is to blame.

How sure are you that the system really is idle? Quite frankly, the constant growing doesn't really look idle to me.

Nothing at all going on in 'ps' during that time? And what does slabinfo say at that point now that kmemleak isn't dominating everything else?
