The pci_epf_ops struct contains a set of callbacks that are used by the pci_epf_driver, and is never modified by the EPF core itself. Marking the struct pointer const allows EPF drivers to declare their pci_epf_ops struct to be const. This allows the struct to be placed in the read-only section. Which for example brings some security benefits as the callbacks can not be overwritten.

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.
