Group some variables based on their sizes to reduce hole and avoid padding. On x86_64, this shrinks the size of 'struct kobject' from 256 to 244 bytes. This structure is often included in some other structures. So these other structures will also benefit from this 8 bytes saving. This is especially nice for structure like 'cma_kobject' or 'class_dir' that are now 256 bytes long. When they are kzalloc()'ed, 256 bytes are allocated, instead of 512.

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.
