Hi-
Here is a second crack at the TEST_STATEID fixes and patches to
implement UCS. I've attempted to address the following review
comments:
o The changes have been reorganized to allow the meaty parts of
the TEST_STATEID fixes to be applied to -stable.
o Additional in-code comments have been introduced.
o FREE_STATEID is now performed in all cases after TEST_STATEID
except when the TEST_STATEID operation result is
NFS4ERR_BAD_STATEID.
o The change to check clp->cl_cons_state in
nfs4_wait_clnt_recover() is now a separate patch with its own
justification.
As before, there is one last bug to fix: rpcauth_create() returns
-EEXIST when replacing an RPC client's rpc_auth, if both the
existing and new rpc_auth are RPC_AUTH_GSS. I should be able to
post a solution for review next week.
The final patch in this series is a hack, posted for discussion.
