Incoming stateid (used by a READ) could be a saved copy stateid. Using the provided stateid, look it up in the list of copy_notify stateids. If found, use the parent's stateid and parent's clid to look up the parent's stid to do the appropriate checks. Update the copy notify timestamp (cpntf_time) with current time this making it 'active' so that laundromat thread will not delete copy notify state.

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.
