Marking the special vnet and dpcpu symbols as weak might be sufficient to stop the relaxations, but I wouldn't like to say for sure, kernel modules get build with weird symbol interposition semantics th= at have always been asking for trouble. --=20 You are receiving this mail because: You are on the CC list for the bug.=
