Subject: NFSv4: Ensure we throw out bad delegation stateids on NFS4ERR_BAD_STATEID
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b9f9a03150969e4bd9967c20bce67c4de769058f;p=linux-beck.git

NFSv4: Ensure we throw out bad delegation stateids on NFS4ERR_BAD_STATEID

To ensure that we don't just reuse the bad delegation when we attempt to
recover the nfs4_state that received the bad stateid error.
