This patch adds a new slab for gfs2 transactions. That allows us to reduce kernel memory fragmentation, have better organization of data for analysis of vmcore dumps. A new centralized function is added to free the slab objects, and it exposes use-after-free by giving warnings if a transaction is freed while it still has bd elements attached to its buffers or ail lists. We make sure to initialize those transaction ail lists so we can check their integrity when freeing. At a later time, we should add a slab initialization function to make it more efficient, but for this initial patch I wanted to minimize the impact.

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.
