This check doesn't save anything. In the case when none of the parameters are present, each strstr will scan args twice (once to find the length and then for searching), six scans in total. Just going ahead and parsing the arguments only requires three scans: strlen, memcpy, and parsing. This will be the first malloc, so free will actually free up the memory, so the check doesn't save heap space either.

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.
