Yes, this seems to be correct and necessary addition. At first sight, the later code shouldn't blow because of that. BTW, buildworld -jN on top of the null mount together with another buildword -jN on the underlying file system helps a lot to discover vnode locking problems. -- Boris Popov http://rbp.euro.ruReceived on Sun Nov 23 2003 - 21:53:59 UTC
