Jakub Sitnicki says: ==================== This series has been split out from "Extend SOCKMAP to store listening sockets" [0]. I think it stands on its own, and makes the latter series smaller, which will make the review easier, hopefully. The essence is that we don't need to do a complicated dance in sk_psock_restore_proto, if we agree that the contract with tcp_update_ulp is to restore callbacks even when the socket doesn't use ULP. This is what tcp_update_ulp currently does, and we just make use of it. Series is accompanied by a test for a particularly tricky case of restoring callbacks when we have both sockmap and tls callbacks configured in sk->sk_prot.

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.
