Trond, please let me know if you want to take these or if I may
handle them through the NFSD tree for v5.15. Thanks.


The purpose of this series is to prepare for the optimization of
svc_process_common() to handle NFSD workloads more efficiently. In
other words, NFSD should be the lubricated common case, and callback
is the use case that takes exceptional paths.

Changes since RFC:
- Removed RQ_DROPME test from nfs_callback_dispatch()
- Restored .pc_encode call-outs to prevent dropped replies
- Fixed whitespace damage

Chuck Lever (7):
      SUNRPC: Add svc_rqst::rq_auth_stat
      SUNRPC: Set rq_auth_stat in the pg_authenticate() callout
      SUNRPC: Eliminate the RQ_AUTHERR flag
      NFS: Add a private local dispatcher for NFSv4 callback operations
      NFS: Remove unused callback void decoder
      NFS: Extract the xdr_init_encode/decode() calls from decode_compound
      NFS: Clean up the synopsis of callback process_op()
