We currently have two forms of operations - small ops and "full" ops (or just ops). The former does not have pointers for some of the less commonly used features (namely dump start/done and policy). The "full" ops, however, still don't contain all the necessary information. In particular the policy is per command ID, while do and dump often accept different attributes. It's also not possible to define different pre_doit and post_doit callbacks for different commands within the family. At the same time a lot of commands do not support dumping and therefore all the dump-related information is wasted space. Create a new command representation which can hold info about a do implementation or a dump implementation, but not both at the same time. Use this new representation on the command execution path (genl_family_rcv_msg) as we either run a do or a dump and don't have to create a "full" op there.

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.
