Merge tag 'nfsd-4.13' of git://linux-nfs.org/~bfields/linux
Pull nfsd updates from Bruce Fields:
"Chuck's RDMA update overhauls the "call receive" side of the
RPC-over-RDMA transport to use the new rdma_rw API.
Christoph cleaned the way nfs operations are declared, removing a
bunch of function-pointer casts and declaring the operation vectors as
const.
Christoph's changes touch both client and server, and both client and
server pulls this time around should be based on the same commits from
Christoph"
