Use correct return value on action creation: ACT_P_CREATED. The use of incorrect return value could result in a situation where the system thought a ctinfo module was listening but actually wasn't instantiated correctly leading to an OOPS in tcf_generic_walker(). Confession time: Until very recently, development of this module has been done on 'net-next' tree to 'clean compile' level with run-time testing on backports to 4.14 & 4.19 kernels under openwrt. During the back & forward porting during development & testing, the critical ACT_P_CREATED return code got missed despite being in the 4.14 & 4.19 backports. I have now gone through the init functions, using act_csum as reference with a fine toothed comb. Bonus, no more OOPSes. I managed to also miss this issue till now due to the new strict nla_parse_nested function failing validation before action creation. As an inexperienced developer I've learned that copy/pasting/backporting/forward porting code correctly is hard. If I ever get to a developer conference I shall don the cone of shame.

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.
