[patch 12/43] NFSD: provide encode routine for OP_OPENATTR

[Greg KH]

2.6.28-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Benny Halevy <bhalevy@xxxxxxxxxxx>

commit 84f09f46b4ee9e4e9b6381f8af31817516d2091b upstream.

Although this operation is unsupported by our implementation
we still need to provide an encode routine for it to
merely encode its (error) status back in the compound reply.

Thanks for Bill Baker at sun.com for testing with the Sun
OpenSolaris' client, finding, and reporting this bug at
Connectathon 2009.

This bug was introduced in 2.6.27
