Linus Torvalds 310c7585e8 Olga added support for the NFSv4.2 asynchronous copy protocol. We
already supported COPY, by copying a limited amount of data and then
 returning a short result, letting the client resend.  The asynchronous
 protocol should offer better performance at the expense of some
 complexity.
 
 The other highlight is Trond's work to convert the duplicate reply cache
 to a red-black tree, and to move it and some other server caches to RCU.
 (Previously these have meant taking global spinlocks on every RPC.)
 
 Otherwise, some RDMA work and miscellaneous bugfixes.
