[AF_UNIX]: Use lookup_create().
currently it opencodes it, but that's in the way of chaning the lookup_hash interface. I'd prefer to disallow modular af_unix over exporting lookup_create, but I'll leave that to you. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: David S. Miller <davem@davemloft.net>
