[PATCH v2 0/5] Fix up delegation reclaim and recovery issues

Trond Myklebust
2014-11-12T22:32:11Z

The main change w.r.t. the first iteration of these patches is that
we no longer trust the NFS_DELEGATED_STATE flag to tell us when we need
to test and/or discard the delegation. Instead, we just assume that
if we have a delegation then it is part of the recovery process.

Trond Myklebust (5):
NFSv4: Ensure that we remove NFSv4.0 delegations when state has
expired
NFSv4.1: nfs41_clear_delegation_stateid shouldn't trust
NFS_DELEGATED_STATE
NFSv4: Fix races between nfs_remove_bad_delegation() and delegation
return
NFSv4: Ensure that we call FREE_STATEID when NFSv4.x stateids are
revoked
NFS: Don't try to reclaim delegation open state if recovery failed
