Use SRCU in a sensible way by removing all MRs in the implicit tree from the two xarrays (the update operation), then a synchronize, followed by a normal single threaded teardown. This is only a little unusual from the normal pattern as there can still be some work pending in the unbound wq that may also require a workqueue flush. This is tracked with a single atomic, consolidating the redundant existing atomics and wait queue. For understand-ability the entire ODP implicit create/destroy flow now largely exists in a single pair of functions within odp.c, with a few support functions for tearing down an unused child.

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.
