Introducing the COPY_NOTIFY operation. Create a new unique stateid that will keep track of the copy state and the upcoming READs that will use that stateid. Each associated parent stateid has a list of copy notify stateids. A copy notify structure makes a copy of the parent stateid and a clientid and will use it to look up the parent stateid during the READ request (suggested by Trond Myklebust <trond.myklebust@hammerspace.com>). At nfs4_put_stid() time, we walk the list of the associated copy notify stateids and delete them. Laundromat thread will traverse globally stored copy notify stateid in idr and notice if any haven't been referenced in the lease period, if so, it'll remove them. Return single netaddr to advertise to the copy.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
