I agree. I'm appalled at mixing the two. I had several years of that at Sun, thank you very much.

CAM and all assocated drives should be MPSAFE. Period. Scott is working on this how.

Yes -- we're beginning to reach the point where we can start issuing ultimatums on device drivers, but need USB and Firewire dealt with before we can begin to push out stragglers. For better or worse, those two hardware categories can't be ignored. Being at a point where we can universally make assumptions about MPSAFEty is a very good place to be, and we're very close with the network stack.

I've been following Scott's CAM work in P4 with great interest, albeit little or no insight, since I know almost nothing about the SCSI layer. My brain is simply too small...
