This patch adds standardized allocation macros and memory tracking tools to track and report any allocated memory that is not freed. This makes it easier to ensure that the vdo target does not leak memory. This patch also adds utilities for controlling whether certain threads are allowed to allocate memory, since memory allocation during certain critical code sections can cause the vdo target to deadlock.

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.
