Matthew Dillon e3a285c715 Make sure file after VOP_OPEN is VMIO'd when transfering control from ... a lower layer to an upper layer. I'm not sure how necessary this is for reading. Fix bug in union_lookup() (note: there are probably still several bugs in union_lookup()). This one set lerror as a side effect without setting lowervp, causing copyup code further on down to crash on a null lowervp pointer. Changed the side effect to use a temporary variable instead.		1999-09-28 05:48:39 +00:00
