Move the debug_obj::object pointer into a union and add a pointer to the last node in a batch. That allows to implement batch processing efficiently by utilizing the stack property of hlist: When the first object of a batch is added to the list, then the batch pointer is set to the hlist node of the object itself. Any subsequent add retrieves the pointer to the last node from the first object in the list and uses that for storing the last node pointer in the newly added object. Add the pointer to the data structure and ensure that all relevant pool sizes are strictly batch sized. The actual batching implementation follows in subsequent changes.

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 reStructuredText 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.
