The reference counting of dax_region objects is needlessly complicated, has lead to confusion [1], and has hidden a bug [2]. While testing the cleanup for those issues, a CONFIG_DEBUG_KOBJECT_RELEASE test run uncovered a use-after-free in dax_mapping_release(). Clean all of that up. Thanks to Yongqiang, Paul, and Ira for their analysis. Additionally, clean up a redundant variable in fsdax, and fix memory hotplug registration in the kmem driver.

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.
