  NFS: Always provide aligned buffers to the RPC read layers
(2021-08-30 13:21:38 -0400)

----------------------------------------------------------------
- New Features:
  - Better client responsiveness when server isn't replying
  - Use refcount_t in sunrpc rpc_client refcount tracking
  - Add srcaddr and dst_port to the sunrpc sysfs info files
  - Add basic support for connection sharing between servers with multiple NICs`

- Bugfixes and Cleanups:
  - Sunrpc tracepoint cleanups
  - Disconnect after ib_post_send() errors to avoid deadlocks
  - Fix for tearing down rpcrdma_reps
  - Fix a potential pNFS layoutget livelock loop
  - pNFS layout barrier fixes
  - Fix a potential memory corruption in rpc_wake_up_queued_task_set_status()
  - Fix reconnection locking
  - Fix return value of get_srcport()
  - Remove rpcrdma_post_sends()
  - Remove pNFS dead code
  - Remove copy size restriction for inter-server copies
  - Overhaul the NFS callback service
  - Clean up sunrpc TCP socket shutdowns
  - Always provide aligned buffers to RPC read layers

Thanks,
Anna
