Subject: nfsd4: assume test_stateid always has session
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=36279ac10c3d69372af875f1affafd375db687a9;p=linux-beck.git

nfsd4: assume test_stateid always has session

Test_stateid is 4.1-only and only allowed after a sequence operation, so
this check is unnecessary.
