6.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Olga Kornievskaia <kolga@xxxxxxxxxx>
[ Upstream commit 4506f23e117161a20104c8fa04f33e1ca63c26af ]
Currently, if the OPEN compound experiencing an error and needs to
get the file attributes separately, it will send a stand alone
GETATTR but it would use the filehandle from the results of
the OPEN compound. In case of the CLAIM_FH OPEN, nfs_openres's fh
is zero value. That generate a GETATTR that's sent with a zero
value filehandle, and results in the server returning an error.
Instead, for the CLAIM_FH OPEN, take the filehandle that was used
in the PUTFH of the OPEN compound.
