H A Dunion_vnops.cdiff f8fc96b55143bb2d621773cf275bb1c1c74ad3b7 Tue Aug 12 09:18:59 CEST 1997 KATO Takenori <kato@FreeBSD.org> Fixed vnode corruption by undefined case in union_lookup(). When
uerror == 0 && lerror == EACCES, lowervp == NULLVP and union_allocvp
doesn't find existing union node and new union node is created.

Sicne it is dificult to cover all the case, union_lookup always
returns when union_lookup1() returns EACCES.
