Highlights include:
Stable fixes:
- SUNRPC: Ensure bvecs are re-synced when we re-encode the RPC request
- Fix an Oops in ff_layout_track_ds_error due to a PTR_ERR() dereference
- Revert buggy NFS readdirplus optimisation
- NFSv4: Handle the special Linux file open access mode
- pnfs: Fix a problem where we gratuitously start doing I/O through the MDS
Features:
- Allow NFS client to set up multiple TCP connections to the server using
a new 'nconnect=X' mount option. Queue length is used to balance load.
- Enhance statistics reporting to report on all transports when using
multiple connections.
- Speed up SUNRPC by removing bh-safe spinlocks
- Add a mechanism to allow NFSv4 to request that containers set a
unique per-host identifier for when the hostname is not set.
- Ensure NFSv4 updates the lease_time after a clientid update
Bugfixes and cleanup:
- Fix use-after-free in rpcrdma_post_recvs
- Fix a memory leak when nfs_match_client() is interrupted
- Fix buggy file access checking in NFSv4 open for execute
- disable unsupported client side deduplication
- Fix spurious client disconnections
- Fix occasional RDMA transport deadlock
- Various RDMA cleanups
- Various tracepoint fixes
- Fix the TCP callback channel to guarantee the server can actually send
the number of callback requests that was negotiated at mount time.
