sys/miscfs/union union_vnops.c
Log:
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.
