mainlining shenanigans

Currently, kmemleak only prints the number of suspected leaks to dmesg but requires the user to read a debugfs file to get the actual stack traces of the objects' allocation points. Add a module option to print the full object information to dmesg too. It can be enabled with kmemleak.verbose=1 on the kernel command line, or "echo 1 > /sys/module/kmemleak/parameters/verbose": This allows easier integration of kmemleak into test systems: We have automated test infrastructure to test our Linux systems. With this option, running our tests with kmemleak is as simple as enabling kmemleak and passing this command line option; the test infrastructure knows how to save kernel logs, which will now include kmemleak reports. Without this option, the test infrastructure needs to be specifically taught to read out the kmemleak debugfs file. Removing this need for special handling makes kmemleak more similar to other kernel debug options (slab debugging, debug objects, etc).

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.
