  pNFS/filelayout: enable LAYOUTGET on OPEN (2019-09-24 16:28:38 -0400)

----------------------------------------------------------------
Stable bugfixes:
- Dequeue the request from the receive queue while we're re-encoding # v4.20+
- Fix buffer handling of GSS MIC without slack # 5.1

Features:
- Increase xprtrdma maximum transport header and slot table sizes
- Add support for nfs4_call_sync() calls using a custom rpc_task_struct
- Optimize the default readahead size
- Enable pNFS filelayout LAYOUTGET on OPEN

Other bugfixes and cleanups:
- Fix possible null-pointer dereferences and memory leaks
- Various NFS over RDMA cleanups
- Various NFS over RDMA comment updates
- Don't receive TCP data into a reset request buffer
- Don't try to parse incomplete RPC messages
- Fix congestion window race with disconnect
- Clean up pNFS return-on-close error handling
- Fixes for NFS4ERR_OLD_STATEID handling

Thanks,
Anna
