Subject: NFSv4: Remove bogus call to nfs4_drop_state_owner() in _nfs4_open_expired()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=35d05778e25ee16dbddb60331be0bc1309efba19;hp=dbae4c73f08b8a7980cc912954ade3d4c1fb6147;p=mv-sheeva.git

NFSv4: Remove bogus call to nfs4_drop_state_owner() in _nfs4_open_expired()

There should be no need to invalidate a perfectly good state owner just
because of a stale filehandle. Doing so can cause the state recovery code
to break, since nfs4_get_renew_cred() and nfs4_get_setclientid_cred() rely
on finding active state owners.
