Subject: nfsd4: fail when delegreturn gets a non-delegation stateid
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=7e0f7cf582abd6c85232331dfe726a4e4b0fd98e;p=linux-2.6-omap-h63xx.git

nfsd4: fail when delegreturn gets a non-delegation stateid

Previous cleanup reveals an obvious (though harmless) bug: when
delegreturn gets a stateid that isn't for a delegation, it should return
an error rather than doing nothing.
