However, I wonder whether it= is too late for this change, as applications can't count on it, especially if = it is optional (and off by default). On the implementation, I wouldn't use VOP_UNP_CONNECT(). It doesn't have s= ide effects now, but that could change. Just testing v_unpcb would be OK. --=20 You are receiving this mail because: You are the assignee for the bug.=
