Yeah, I saw that request and was looking into what it would actually take to remove ctl(4) from GENERICs in stable/9. Unfortunately, it's not exactly as straight forward as MFCing the two above revisions 1:1. For one, IMO kern.cam.ctl.disable shouldn't be removed there in case someone uses an old kernel configuration file having "device ctl" but relies on that tunable to work. That's no big deal, though, and makes the merge even less intrusive. However, the real problem is that ctl.ko currently is globally disabled in stable/9 as it doesn't build with PAE/ XEN. Actually, the compiler is right to complain as a 32-bit void-pointer is casted to a 64-bit integer in that case. What I don't get so far is why on earth this doesn't break compilation in head ...
