#     Merge tag 'nfs-for-4.20-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
#     
#     Pull NFS client updates from Trond Myklebust:
#      "Highlights include:
#     
#       Stable fixes:
#        - Fix the NFSv4.1 r/wsize sanity checking
#        - Reset the RPC/RDMA credit grant properly after a disconnect
#        - Fix a missed page unlock after pg_doio()
#     
#       Features and optimisations:
#        - Overhaul of the RPC client socket code to eliminate a locking
#          bottleneck and reduce the latency when transmitting lots of
#          requests in parallel.
#        - Allow parallelisation of the RPCSEC_GSS encoding of an RPC request.
#        - Convert the RPC client socket receive code to use iovec_iter() for
#          improved efficiency.
#        - Convert several NFS and RPC lookup operations to use RCU instead of
#          taking global locks.
#        - Avoid the need for BH-safe locks in the RPC/RDMA back channel.
#     
#       Bugfixes and cleanups:
#        - Fix lock recovery during NFSv4 delegation recalls
#        - Fix the NFSv4 + NFSv4.1 "lookup revalidate + open file" case.
#        - Fixes for the RPC connection metrics
#        - Various RPC client layer cleanups to consolidate stream based
#          sockets
#        - RPC/RDMA connection cleanups
#        - Simplify the RPC/RDMA cleanup after memory operation failures
#        - Clean ups for NFS v4.2 copy completion and NFSv4 open state
#          reclaim"
