The rtl8188 driver starts a command thread that reads commands from a queue and processes them. Each command consists of a struct cmd_obj. The command thread may call a function to process the current command and optionally a post-processing function. Eventually, the command's cmd_obj must be freed. At the moment, if there's a post-processing function for the current command, this function has to free the cmd_obj. If there's no post-processing function, the command thread frees cmd_obj. It's much simpler if we always leave it to the command thread to free cmd_obj.

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.
