# Merge: 9b190ecca11c 93f38b6fae0e
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'nfsd-4.20' of git://linux-nfs.org/~bfields/linux
#     
#     Pull nfsd updates from Bruce Fields:
#      "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"
