For debugging purposes it is useful to assign descriptions
to buffers so that we know what they are used for. Add
a field to the buffer object and use that to name the various
kernel side allocations which ends up looking like like this
in /d/dri/X/gem:
flags id ref offset kaddr size madv name
00040000: I 0 ( 1) 00000000 0000000070b79eca 00004096 memptrs
vmas: [gpu: 01000000,mapped,inuse=1]
00020000: I 0 ( 1) 00000000 0000000031ed4074 00032768 ring0

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.
