Section .static_call_sites holds data structures that need to be sorted and processed only at module load time. This initial processing happens in static_call_add_module(), which is invoked as a callback to the MODULE_STATE_COMING notification from prepare_coming_module(). The section is never modified afterwards. Make it therefore read-only after module initialization to avoid any (non-)accidental modifications.

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.
