The size of struct pdu is 8 byte. The memory is allocated, initialized, used and deallocated a few lines later. It is more efficient to avoid the allocation/free dance and assign the values directly to skb's data part instead of using memcpy() for it. Avoid an allocation of struct pdu and use the resulting skb pointer instead.

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.
