SUNRPC: Convert the auth cred cache to use refcount_t (2018-10-23 12:24:33 -0400)
Cheers

----------------------------------------------------------------
NFS client updates for Linux 4.20
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.
