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.

Pulled.
Btw, just out of curiosity - is there some pattern to when I get the
pull requests from you vs Anna? Or is it just "whoever happens to have
the baton"? Not that it matters, but I was wondering if there was some
logic to it that I've missed..

Thank you!

We agreed about a year or so ago to take turns maintaining the linux-
next branches. So in practice that means Anna has been sending you the
pull requests for the odd kernel minor numbers, and I've been sending
you the ones for the even numbers.
We still share the burden of reviewing the code, though, so if
something slips through the cracks, we get to share the blame... ☺
Cheers

Heh. That was a simpler pattern than I thought. It was just hidden by
the fact that there are sometimes more than one pull request during
the merge window, and then a variable number of "fixes" pull requests
during the rc's..
But now that you mention it I can see that yeah, it just alternates by
releases..
