Given the entire discussions it might well be better suited in sys/contrib/ofed under the assumtion that the code is mostly maintained outside our tree and we get in occational updates. I hadn't quite liked the sys/cddl but given that we had sys/gnu as well. And then there is sys/compat. I wonder if you could still or maybe not make the shim layer something like it's own .ko kind of like opensolaris.ko (you cannot name it linux.ko though;) I guess similarly things in user space might go to contrib as well? Would you by any chance be able to generate a patch for all the sys/ and config etc. changes outside the ofed directory for prior review by people? I am just fearing that there might be bits for the V_irtualization side etc to consider, as might be for others with outstanding work. Thanks, /bz -- Bjoern A. Zeeb You have to have visions!
