'n_tables' is small, UDP_TUNNEL_NIC_MAX_TABLES = 4 as a maximum. So there is no real point to allocate the 'entries' pointers array with a dedicate memory allocation. Using a flexible array for struct udp_tunnel_nic->entries avoids the overhead of an additional memory allocation. This also saves an indirection when the array is accessed. Finally, __counted_by() can be used for run-time bounds checking if configured and supported by the compiler.

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.
