The bpf_net_ctx_get_.*_flush_list() are used at the top of the function. This means the variable is always assigned even if unused. By moving the function to where it is used, it is possible to delay the initialisation until it is unavoidable. Not sure how much this gains in reality but by looking at bq_enqueue() (in devmap.c) gcc pushes one register less to the stack. \o/. Move flush list retrieval to where it is used.

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 reStructuredText 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.
