As long as CURRENT revision is > < r335873, > those kmod compile well. The virtualbox-ose-kmod issue is different. It's namespace pollution caused by the inclusion of sys/param.h in sys/systm.h when _KERNEL is defined. sys/param.h includes sys/priority.h if LOCORE is not defined. virtualbox typedefs PVM as a struct whereas sys/priority.h defines it as a constant. Virtualbox undefines PVM in some headers, usually after including sys/param.h. I haven't looked at it further than this with the limited time I have tonight but I suspect one of the #undef PVM statements needs to move. > - -- > O.
